ASTM A268 TP446-1/Sandvik 4C54

Sandvik 4C54 is a ferritic, heat resisting, stainless chromium steel, characterized by:Sandvik 4C54是一种铁素体耐热不锈钢，其特点是：

– Extremely good resistance to reducing sulphurous gases对减少含硫气体有极好的抵抗力

– Very good resistance to oxidation in air良好的抗空气氧化性能

– Good resistance to oil-ash corrosion耐油灰腐蚀

– Good resistance to molten copper, lead and tin良好的抗熔铜、铅和锡的性能

This steel can be used at temperatures up to 1100°C (2010°F). However, allowance should be made for low creep strength at the highest temperatures in order to avoid distortion due to the mass of the steel.这种钢可在1100°C(2010°F)的温度下使用。然而，在最高温度下，应考虑到较低的蠕变强度，以避免由于s的质量而引起的变形。
