1, 304

18Cr-8Ni, as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; stamping, bending and other thermal processing properties, no heat treatment hardening (no magnetic, using temperature -196 C ~800). Household items (1 and 2 types of tableware, cupboards, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, moulds), medical appliances, building materials, chemistry, food industry, agriculture, ship parts

2, 304L

18Cr-8Ni- low carbon as low C 304 steel, in general state, its corrosion resistance is similar to that of 304, but after welding or eliminating stress, its resistance to grain boundary corrosion is excellent. In the absence of heat treatment, it can also maintain good corrosion resistance and use temperature -196 C ~800 C. It is applied to open-pit machines, building materials, heat-resistant parts and difficult parts for heat treatment, which are highly resistant to grain boundary corrosion.

3, 321

18Cr-9Ni-Ti added Ti element to 304 steel to prevent grain boundary corrosion. It is suitable for use at 430 -900 C temperature. Aircraft, exhaust pipe, boiler drum

4, 309S

The highest temperature resistance of stainless steel 309S is high nitrogen austenite resistance temperature 1200 degrees 310S and 309S are high nitrogen austenitic stainless steel, chemical properties and ingredients are similar, if continuous temperature is 1150 degrees with temperature.

5, 310S: (0Cr25Ni20)

Characteristics: suitable for all kinds of furnace components, the highest temperature is 1200 C, and the continuous use temperature is 1150 C.

Uses: materials for furnace, materials for vehicle purification, aerospace and petrochemical industry.
