An austenitic stainless steel grade (300 series), with a lower nickel content giving it a higher work-hardening rate — used where cold-worked strength matters.

An austenitic stainless steel grade (300 series), slightly higher in chromium and nickel than 301 for improved corrosion resistance.

An austenitic stainless steel grade (300 series), free-machining — not typically supplied as tube.

The most widely used austenitic stainless grade, offering good general corrosion resistance with 18–20% chromium and 8–10.5% nickel.

The low-carbon variant of 304, used where welding may otherwise cause sensitization in a corrosive environment.

An austenitic stainless steel grade (300 series), with a higher carbon floor than 304 for improved high-temperature strength.

An austenitic stainless steel grade (300 series), primarily used as a weld-filler composition.

An austenitic stainless steel grade (300 series), with higher chromium-nickel content for improved high-temperature oxidation resistance.

With 24–26% chromium and 19–22% nickel — significantly higher than 304 or 316 — 310 offers excellent resistance to oxidation and scaling at sustained high temperatures.

An austenitic stainless steel grade (300 series), with a high-silicon addition for high-temperature service.

Adds 2–3% molybdenum to the 304-type composition, significantly improving resistance to pitting and crevice corrosion in chloride-containing environments.

An austenitic stainless steel grade (300 series), a titanium-stabilized variant of 316.

An austenitic stainless steel grade (300 series), with higher molybdenum than 316 for further improved chloride resistance.

Titanium-stabilized, which prevents chromium carbide precipitation (sensitization) during welding and sustained exposure to 427–816°C.

A high-nickel transitional grade (300 series numbering) with strong carburization resistance.

An austenitic stainless steel grade (300 series), niobium-stabilized as an alternative to 321.

An austenitic stainless steel grade (300 series), with a low work-hardening rate suited to cold heading.

The highest-chromium common ferritic stainless steel grade (400 series), with the strongest oxidation resistance in the family.

A martensitic stainless steel grade (400 series), the basic hardenable grade in the family; 403 is a turbine-quality variant of 410.

A martensitic stainless steel grade (400 series), nickel-added over 410 for improved toughness.

A martensitic stainless steel grade (400 series), a free-machining variant of 410.

A martensitic stainless steel grade (400 series), with higher carbon than 410 for greater hardness.

A chromium-nickel martensitic stainless steel grade (400 series), with higher strength than 410/414.

The highest-carbon common martensitic stainless steel grade (400 series), for maximum hardness.

An austenitic stainless steel grade using manganese in place of some nickel (200 series), reducing cost at some expense of corrosion resistance.

An austenitic stainless steel grade using manganese in place of some nickel (200 series), a similar cost-saving substitution to 201 with a slightly different balance.

A duplex (austenitic-ferritic) stainless steel grade, combining higher strength than standard austenitic grades with strong corrosion resistance.

A lean duplex (austenitic-ferritic) stainless steel grade, with lower molybdenum than 2205.
