A240 304L 2B Stainless coil 304L 2B sheets
We export ASTM A240 304L 2B,A240 304L 2B surface stainless steel, stainless sheets and cutting parts. The 304L surface 304L 2D/304l DF(304L 1/2H、304L 3/4H、304l H) 304L BA/2BB and 304L HL. The max width 1500mm, the max thickness 5mm in Cold rolled situation
What is A240 304L 2B Stainless coil?
304L 2B refers to the surface of stainless steel, on behalf of the fog surface, also called 304L 2B fog surface, according to the figure. The 304L 2B surface stainless steel is soft, that is, the hardness of 304L HV(Vickers hardness) in 150-200 degrees. The order is 3042B surface, matte surface, bright surface, 304BA surface, 304L 6K, 304 8K. 304BA is now a mirror.
304L 2B surface is the fog surface, according to the figure, object, refers to a surface effect of stainless steel, in addition to 2B surface, BA surface, mirror

A240 304L 2B application
304L 2B stainless steel is the most widely used a kind of chrome-nickel stainless steel, as a kind of widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical characteristics; Good thermal processing property such as punching and bending, no hardening phenomenon of heat treatment (using temperature -196℃ ~ 800℃). Corrosion resistance in the atmosphere, if it is industrial atmosphere or heavily polluted areas, it is necessary to clean in time to avoid corrosion. Suitable for food processing, storage and transportation. It has good machining performance and weldability. Plate heat exchanger, bellows, household products (Class 1, 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, mold products), medical appliances, building materials, chemistry, food industry, agriculture, Marine parts, etc. The content of 304L stainless steel is strictly controlled, which can also be called food grade 304L 2B stainless steel
