Wing Kam started develop a series of high temperature resistant alloy parts such as A20, SS310, this special stainless steel has a good oxidation resistance and corrosion resistance, which contains a high percentage of chromium and nickel, has a good creep strength, can continue to work at high temperature, has a good high temperature resistance. This kind of stainless steel is widely used in petroleum, chemical, medicine, shipbuilding, nuclear power, military, machinery, environmental protection, etc.

At the beginning of the special material development, to meet customer demand for high-performance stainless steel, we overcome alloy casting performance is poor, the product structure is complex, poor welding performance is difficult, after several months of efforts, we finally curing special alloy by investment casting and sand casting processes, got the customer’s approval and brought a series of new product development. In early April, the sand casting workshop successively developed DIN 1.4826 1.4837 1.4848 material products, and successfully to the customer delivery, results show that the more hard conditions,The more able to inspire fighting spirit, catalytic results.
