ASME SA269 TP304 1.4301奥氏体无缝光亮退火管
优势：
ASME SA269 TP304光亮退火管在没有氯化物和氟化物的腐蚀性溶液中表现良好。它们还具有优异的成形和焊接特性，并在腐蚀性环境中表现出良好的性能。无缝管还可以承受更高的压力。
ASME SA269 TP304是一种奥氏体级钢，包括标准无缝和焊接配置。ASME SA269 TP304卡套管采用镍和铬与其他构成合金的优异成分设计，增强了这些卡套管对腐蚀和氧化介质的抵抗力。
ASME SA269 TP304不锈钢卡套管的密度为8g/cm³，熔点为1400摄氏度。这些卡套管具有优异的机械性能，可以在不同的压力和温度下工作。
