305 STAINLESS STEEL ALLOY

UNS: S30500
EN-DIN: 1.4303


Industries supplied include: appliances, kitchen utensils, tank covers, and other deep drawn parts. 305 grade stainless has similar corrosion resistance as 304 and has good oxidation resistance in air up to 1650 F (899 C). 305 can be readily formed and deep drawn into complex shapes due to its lower strength and work hardening rate and will remain nonmagnetic after cold work unlike 301 or 304. A caution is autogenous welds in 305 are more sensitive to hot cracking than 304 or 304L.

Additional Information on 305 Stainless Steel

We produce all of our stainless steel using the highest quality processes and materials. Our aim is to provide you with high quality metal that is competitively priced, carefully packaged, and delivered in spec and on time. One such high quality item is type 305 stainless steel, which we will go into detail on after first considering the primary types of stainless steel.


Properties of Type 305 Stainless Steel

Stainless Steel type 305 is an austenitic Chromium-Nickel alloy with a low rate of work hardening that makes it a good choice for many deep drawing applications. When ordering 305 stainless steel, note the deep drawing quality. Ordering annealed or dead soft will not guarantee this however. This alloy is non-magnetic but will slowly become so with increasing cold work.


Processing & Forming of 305 Stainless Steel

Type 305 is an austenitic, Chromium-Nickel stainless steel alloy with an increased Nickel content that allows it to be spun and deep drawn easily while decreasing work hardening. Stainless steel 305 cannot be hardened by heat treatment.


Unlike Type 301 and 304, Type 305 stainless steel remains non-magnetic after cold work. It can be readily formed and deep drawn into complex shapes due to its lower strength and hardening rates. It is used for a wide variety of products in the chemical, textile, petroleum, dairy, and food industries.
