Good Corrosion Resistance Seamless Tube ASTM A268 TP430 1.4016
ASTM A268 is a Standard specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service, the grades contain TP410, TP405, TP420, TP430, TP430Ti, TP403, TP409, TP444, TP439 and TP446.
本规范涵盖多种公称壁厚等级的不锈钢管,用于一般耐腐蚀和高温环境。这些牌号中的大多数通常被称为 "直铬 "型,其特点是具有铁磁性。其中两种
TP410 和 UNS S41500 等牌号可通过热处理硬化,而高铬铁素体合金在缓慢冷却至普通温度时容易产生缺口脆性。在使用这些材料时应认识到这些特点。
钢管必须采用无缝或焊接工艺制造,不得添加填充金属,钢管必须重新加热至 1200 华氏度 [650 摄氏度] 或更高温度,并冷却至符合本规范要求,所有钢管必须没有过多的轧制鳞片,适合检查。轻微的氧化不视为水垢。
430 Stainless Steel is a low-carbon plain chromium ferritic stainless steel. The steel has good corrosion resistance in mildly corrosive environments and good resistance to oxidation at elevated temperature. In the annealed condition the steel is ductile, does not harden excessively during cold work and can be formed using a large variety of roll forming or mild stretch-bending operations, as well as the more common drawing and bending processes.
