12Cr1MoV Alloy structural steel. Standard: GB/T3077-2015, which is a high-performance alloy material. It is a steel type widely used in superheaters, headers and main steam ducts of high-pressure, ultra-high-pressure and subcritical power station boilers. It still has high thermal strength and oxidation resistance at 580, and has high lasting plasticity. 15CrMo steel is a heat-resistant steel with a pearlite structure. It has high thermal strength (�´bâ?¥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. Since the steel contains high content of Cr, C and other alloying elements, the steel has an obvious hardening tendency and poor weld ability.we Deals in: SPECIAL STEEL 1.MEDIUM-HIGH CARBON STEEL:( AISI1010,1020,1035,1045,1050,1055,CK45,XC45,XC48TS,XC55 ) 2.HIGH CARBON STEEL:(S10C,S20C,S35C,S45C,S50C,S55C) 3.HIGH WEAR RESISTANCE STEEL:( HARDOX 400, HARDOX 450.
