Silicon and molybdenum, tungsten, chromium and other separation, has improved corrosion resistance and anti-oxidation effect, can produce heat-resistantsteel.
硅和钼、钨、铬等分离，有进步抗腐蚀性和抗氧化的作用，可制造耐热钢。
2
Chromium can improve the oxidation resistance and corrosion resistance of steel, so it is an important alloying element in stainless steel and heat-resistantsteel.
铬又能进步钢的抗氧化性和耐腐蚀性，因此是不锈钢，耐热钢的重要合金元素。
3
The residual deleterious elements in steel lead to products occurring red brittleness surface crack and temper brittleness, and lead to hot strength of heatresistantsteel decreasing.
