Adaptation environment and precautions of stainless steel chain materials

Chain material Austenitic stainless steel

(304/304L) Austenitic stainless steel

(316/316L)

Features The most widely used stainless steel chain for special environments, the corrosion resistance is much better than 304 stainless steel chain

Operating environment (1) The most widely used stainless steel chain for special environments

(2) Environment with water

(3) A clean environment (1) All special environments for 304 stainless steel chains

(2) Environments with high chloride ion concentration such as sea water and seashore

(1) Suitable for corrosive environment,

Including food, chemistry, medicine,

Part of acid, alkali or corrosive liquid, etc.

(2) Suitable for high temperature and low temperature environment (-20℃-400℃) (1) Highly corrosive industrial atmosphere

(2) Pulp or papermaking equipment or environment

(3) Certain concentration of hydrochloric acid and sulfuric acid

Strong acid environment

(4) A non-magnetic environment is required

Note (1) The tensile strength is low, the wear life is low, and it cannot be strengthened by heat treatment

(2) Improve corrosion resistance through solution treatment

(3) Generally weak magnetic

(4) It is easy to produce intergranular corrosion at 425℃-815℃,

Should avoid working in the temperature range, such as unavoidable or welding

And can not be heat treated after welding, 304L with carbon content ≤0.03% should be used

(5) Stress corrosion fracture will occur under the conditions of chloride ion, tensile stress and high temperature.

Choose 316L with carbon content ≤0.03%
