Stainless Steel Grade 422 is a hardenable martensitic stainless steel which is being widely used for high temperatures up to 1200°F. It has excellent creep-rupture properties in the range of 600/1200°F and is capable of being heat treated to various high strength levels depending on section, form, and application involved.

Type 422 offers designers in the aircraft and power industries high strength/weight ratios from room temperature to 1200°F. The composition is carefully balanced to provide a microstructure which is virtually all tempered martensite after heat treatment. This structure assures uniformity of mechanical properties with a minimum of directionality.

316LVM F-138 is regarded as the ‘Medical Stainless Steel Grade’. This stainless steel 316 Vacuum Arc-Remelted (VAR) to achieve the extremely high levels of purity and ‘cleanliness’ required for surgical implants. It has excellent resistance in physiological environments, to general and intergranular corrosion, to pitting and crevice corrosion.

The ASTM F138 specification signifies implant grade. It is mainly used for permanent implants. 316LVM corrosion resistance is improved by a reduced carbon content compared to the 300 series alloy grades.

316LVM is centerless ground and has a highly polished appearance.

Specifications:

Grade 316 Stainless Steel  is the standard molybdenum-bearing grade. The molybdenum gives 316 better overall corrosion resistant properties than Grades 302 and 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. It is readily brake or roll formed into parts for applications in the industrial, architectural, and transportation fields. Grade 316 also has outstanding welding characteristics.

Grade 316L is low carbon version of 316 and is immune from sensitization (grain boundary carbide precipitation) so it can be used in heavy gauge welded components (over about 6mm).

Grade 316H has a higher carbon content and is used at elevated temperatures, as does stabilized grade 316Ti.

The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.

Stainless grade 304 is produced in various carbon levels. We stock T304, T304L (low carbon) and T304H (high carbon) in a wide range of gauges and finishes. We also stock 304/304L Dual Certified.

304L has a maximum carbon content of .03%. 304H has a carbon content between .04% and .08%

Grade 304 is the standard “18-8” stainless. It is the most versatile and most widely used stainless steel, available in a wider range of products, forms (bar, sheet, plate, tube, coil, etc.) and finishes (Pump shaft quality “PSQ”, Centerless Ground, 2B, etc), than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans, handlebar, hooks, and chains. Grade 304 is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. It also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.Grade 304L, the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge components (over about 6mm).

Grade 304H with its higher carbon content finds application at elevated temperatures. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.

These properties are specified for ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications.

Grade 304 cannot be hardened by thermal treatment.

Stainless steel grade 303 is the most readily machineable of all the austenitic grades of stainless steel.

Type 303 has mechanical properties that are comparable to both 304 and 316 stainless. The primary reason to use 303 is when you need a stainless steel with machining capabilites better than that of 304 and 316. It has roughly the same corrosion resistance as 304, but not as good as 316. The main drawback with the alloy is that it is not generally considered to be weldable. This material is hardenable by cold work.

The machineable nature of Grade 303 stainless steel is due to the presence of Sulphur in the steels composition. While the Sulphur improves machining, it also causes a decrease in the corrosion resistance and a slight lowering of the toughness. The corrosion resistance of grade 303 stainless steel is lower than that for 304. The toughness is still excellent as with other austenitic grades.

Property data given in this document is typical for bar products covered by ASTM A582. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this article.

Sulphur is an addition to the composition act as initiation sites for pitting corrosion. This decreases the corrosion resistance of grade 303 stainless steel to less than that for 304. However corrosion resistance remains good in mild environments.

In chloride containing environments over 60°C, grade 303 stainless steel is subject to pitting and crevice corrosion. Grade 303 stainless is not suitable for use in marine environments.

Grade 303 stainless steel has good resistance to oxidation when intermittently exposed to temperature up to 760°C temperatures. It also has good oxidation resistance in continuous service to 870°C. This, however, is not recommended as 303 is sensitive to carbide precipitation with continuous use at 425-860°C.

Fabrication of all stainless steels should be done only with tools dedicated to stainless steel materials. Tooling and work surfaces must be thoroughly cleaned before each use, as this is necessary to avoid cross contamination of stainless steel.

Type 303 is not readily cold workable but it has excellent machinability.

17-4 stainless steel ( Grade 630 )  is an age-hardening martensitic alloy combining high strength with the corrosion resistance of stainless steel. Hardening is achieved by a short-time, simple low-temperature treatment. Unlike conventional martensitic stainless steels, such as type 410, 17-4 stainless steel is quite weldable. The strength, corrosion resistance and simplified fabrication can make 17-4 stainless steel a cost-effective replacement for high strength carbon steels as well as other stainless grades.

A286 is a precipitation age-hardening iron-nickel-chromium alloy that is one of the most popular and widely used of high temperature alloys. It maintains good strength with oxidation resistance at temperatures of up to 1300F. A286 is used in various components, such as aircraft and industrial gas turbines due to is high strength and superior fabrication. A286 is also very popular in offshore oil and gas industry where high levels of heat and stress are a factor.

The work hardening of A286 is equivalent to 310S Stainless, and cold working is possible at the same level.

A286 has superior corrosion resistance beyond the standard 304 and 304L. This does not change after the aging process.

A286 is harder to work with than 316 and 310 stainless, however A286 can still be cold-worked with positive results. However, compared with other high-temperature alloys A286 is much easier to machine.

303Se Stainless Steel is a free machining 18-8 chrome-nickel steel. Selenium, added to an 18-8 stainless steel that is tough and difficult to machine, makes it so easily and freely machinable that it can be readily be handled on automatic screw machines. It can be machined at about 75% of the speed of carbon C1212. This material has displayed nongalling properties that make disassembly of parts easy and help to avoid scratching or galling in its moving parts.

Type 303Se has somewhat better formability than Stainless Type 303 and should be considered for applications which involve cold-forming operations.

Type 303Se can been used for parts that are fabricated by machining, grinding and polishing. For example, all types of screw machine products, valves, valve trim, etc. However, it is not recommended for vessels containing gases or liquids under high pressure.

Stainless Type 303Se is resistant to atmospheric corrosion, foodstuffs, sterilizing solutions, many organic chemicals and dyestuffs, and a wide variety of inorganic chemicals.

Intergranular corrosion may be a problem if the material is heated between 800ºF (427ºC) and 1650ºF (899ºC) or cooled slowly through that range.

For optimum corrosion resistance, surfaces must be free of scale, lubricants, foreign particles, and coatings applied for drawing and heading. After fabrication of parts, cleaning and/or passivation should be considered.
