304 And 316 Stainless Steel

Nov 30, 2021

Common Sense of 304 and 316 Stainless Steel:

 

304 Stainless Steel

18Cr-8Ni


As a widely used steel, it has good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties; it has good hot workability such as stamping and bending, and no heat treatment hardening phenomenon (non-magnetic, use temperature -196℃~ 800°C).


Household products (category 1, 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical appliances, building materials, chemicals, food industry, agriculture, and ship parts.

 

304L Stainless Steel

18Cr-8Ni-low carbon


As a low-C 304 steel, its corrosion resistance is similar to that of 304 under normal conditions, but after welding or stress relief, its resistance to intergranular corrosion is excellent; it can also maintain good resistance without heat treatment Corrosion resistance, use temperature -196℃~800.


It is applied to outdoor machines in the chemical, coal, and petroleum industries that require high grain boundary corrosion resistance, heat-resistant parts for building materials, and parts with difficult heat treatment.

 

316 Stainless Steel

18Cr-12Ni-2.5Mo


Because of the addition of Mo, its corrosion resistance, atmospheric corrosion resistance, and high-temperature strength are particularly good, and it can be used under harsh conditions; it has excellent work hardening properties (non-magnetic).


Equipment used in seawater, chemical, dye, paper, oxalic acid, fertilizer, and other production equipment; photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts.

 

316L Stainless Steel

18Cr-12Ni-2.5Mo low carbon


As a low-C series of 316 steel, in addition to having the same characteristics as 316 steel, it has excellent grain boundary corrosion resistance.


Among the uses of 316 steel, products with special requirements for resistance to grain boundary corrosion.
