ASTM A335 / ASME SA335 P9 SEAMLESS ALLOY STEEL SMLS PIPE

A335/SA335 P9 is a seamless ferritic alloy-steel pipe used for high-temperature applications. These pipes are versatile and can be used to transmit water, oil and natural gas.



Key to the composition of chrome moly alloy P9 is the addition of chromium and molybdenum. Chromium, or chrome, improves high-temperature strength, increases oxidation resistance and raises the tensile, yield and hardness at room temperatures. Molybdenum increases the strength, elastic limit, resistance to wear, impact qualities and hardenability. It increases the resistance to softening, restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is also the most effective additive for increasing high temperature creep strength, or creep resistance. It also enhances the corrosion resistance of steel and inhibits pitting.

 

众所周知,这两种元素都能提高钢管的耐磨性、抗冲击性、淬透性和弹性极限。它们还能提高管材的机械性能,例如:防止晶粒长大、降低脆性、提高高温蠕变强度并具有出色的抗软化能力。

 

a335 p9 管材中的铬含量使其具有很强的耐腐蚀性。因此,a335 p9 在高温下具有出色的抗氧化性。除铬外,外涂黑油漆或防锈油的 astm a335 p9 合金钢管也具有良好的耐腐蚀性。也可以进行镀锌处理。镀锌可增强其抗大气腐蚀的能力。

 

A335 P9 管材可通过热加工或冷拔成型制造。成型后,钢管必须进行热处理,包括完全退火或等温退火、正火和回火。SA335 P9 级钢管分为四种类型:焊接钢管、加工钢管、无缝钢管和 ERW 钢管。 管道有螺纹端、普通端和斜面端可供选择。这些管材的两端都有塑料盖保护。asme sa335 grade p9 管材和钢管有多种制造形式,如矩形、盘管、圆形、方形、液压管、U 形管和薄饼盘管。
