440C stainless steel stockholders and suppliers, delivering to the whole of the UK. West Yorkshire Steel are suppliers of 440C stainless steel in round bar, diameters. 440C grade provides good wear resistance combined with moderate corrosion resistance in mild environments and has excellent hardenability. 440C is very similar to the 440B grade but with a slightly higher carbon content. It attains a higher hardness than that of 440B but with a slight reduction in its corrosive properties. It can achieve a hardness of up to 60 Rockwell HRc. It resists corrosion in normal domestic environments and very mild industrial environments, with optimum corrosion resistance achieved with a temper below about 400°C. To achieve best corrosion resistance, surfaces must be free of scale, lubricants, foreign particles, and coatings applied for drawing and heading. With its high carbon content 440C annealed stainless machines similar to a high speed steel annealed grade.
