heat-resisting steel

It is urgent require to study friction welding of high temperature alloy and heat-resisting steel, which used in hot dynamical parts of tank, vessel engine, etc.

高温合金与耐热钢的摩擦焊接成型与控制是坦克、舰船发动机等热动力部件连接发展的迫切需要。

the key for super-critical and super super-critical boiler manufacturing is to develop the high-tensile and heat-resistant steel with good high-temperature and process performance. t23 ( p23) steel is a new type heat-resisting steel used for boiler, which is developed overseas in recent years.

超临界和超超临界锅炉发展的关键是开发具有良好高温性能和工艺性能的高强耐热钢，SA213T23和SA335P23（以下简称T23、P23）钢是国外近年来开发研制的锅炉用新型高强耐热钢。

A specific coated-electrode is developed for the new heat-resisting steel ( ZG3Cr_ ( 31) Ni_ ( 11) N) in this paper.

本文介绍了适合焊接新研制出的1200℃炉用耐热钢ZG3Cr（31）Ni（11）的一种专用焊条。
