Stainless Steel

  Since stainless steel is harder and tougher than iron (mild steel), the power of the machine and the hardness of the blade are required for processing such as cutting, shaping, and bending. In addition to the high material cost compared to iron, the reason why stainless steel products are expensive is largely due to the difficulty of this processing.   Below, here are typically stainless steel types.   1-1. SUS304   SUS304: This content may be expressed as 18-8 stainless steel. It has good corrosion resistance and heat resistance and is most commonly used. In addition, various shapes such as plates, pipes, angles, and round bars are made and easily available. Corrosion occurs in environments with strong chlorine and acid. Corrosion cracking may also occur where it is affected by the heat of welding. As a guide, the heat resistant temperature is 500 to 600 ° C.   1-2. SUS316   SUS316: A steel grade based on SUS304 with an increased amount of Ni and 2 to 3% molybdenum added. The additi
