Characteristic: 316 stainless steel is a kind of austenitic stainless steel. Because of the addition of Mo element, its corrosion resistance and high temperature strength are greatly improved. The high temperature resistance can reach 1200-1300 degrees, which can be used under strict condition.
Use: 316 stainless steel is mainly used for heat exchanger machine on pulp and paper making, dyeing equipment, film processing equipment, pipelines, materials for the exterior of buildings in coastal areas. In 2013, it was also used in the field of solenoid valve, mainly used in shell, clamp, ball, valve body, valve seat, nut, valve rod, etc.
Characteristic: 303 stainless steel is an austenitic type acid steel with feature of easy cutting and wear resistant . In order to improve the properties of the steel, no more than 0.60% molybdenum can be added into the steel, which is ablative resistant.
After annealing, the tensile strength of 303 stainless steel is 515mpa, the curvature is 205mpa, and the elongation is 40%. Standard hardness of stainless steel 303 is HRB 90-100, HRC 20-25 (note: hrb100 = hrc22.9).
Use: 303 stainless steel is a kind of free cutting stainless steel containing sulfur and selenium, which is mainly used in the products requiring easy cutting feature and high surface finish. 303 stainless steel has higher cutting performance and higher temperature resistance. It is most suitable for automatic lathes, bolts and nuts.
Characteristic: 304 stainless steel is a common stainless steel material, with a density of 7.93 g / cm3, also called 18 / 8 stainless steel. It has high temperature resistance 800 ℃, good processing performance and high toughness.
Use: 304 stainless steel is widely used in industry, furniture decoration industry,and food and medical industry.
Characteristic: 201 stainless steel, with feature of acid and alkali resistance, high density, polishing without bubbles, pinholes and other characteristics.
Use: It is mainly used to make decorative pipe, industrial pipe and some shallow stretchedproducts.
