Steel plate P690QH,boiler steel plate P690QH
Source:Xin Steel Industry Date:2012/11/13
With the minimum yield strength at 690 Mpa for steel thickness equal and belows 50mm,weldable fine grain boiler steel plate P690QH is mainly used to manufacture liquid boilers and pressure vessels&tanks in heavy industry all over the world.For improving the steel welding properity, excessive post weld heat treatment conditions can decrease the mechanical properties.So our engineers recommended that the end user would like to add this test PWHT as an additional technical terms when they purchase boiler steel plate p690qh.
