S355J0 and SA572 Grade 60 steel, The wear-resistant composite plate is quenched once and tempered at low temperature. The quenching temperature is 820-850℃ or 780-810℃. If the strength of the core is required to be higher, it should be quenched at 820-850℃ with low carbon M at the core. If the surface hardness is required to be high, the grain size can be refined by quenching at 780-810℃. It is suitable for solid carburized carbon steel and low alloy hardfacing wear-resistant composite plate workpieces, and coarse grain steel carburized by gas and liquid.
As a pipeline of oil and natural gas, spiral pipe has its own characteristics: 1. The amount of use is large, because the specifications of S355J0 and SA572 Grade 60 steel, spiral pipe used in a project are often diversified. During the forming process of the spiral pipe, the steel plate deforms evenly, the residual stress is small, and the surface does not occure scratches. 2. The spiral pipe is used in a complex environment, and the quality must be guaranteed, otherwise it will delay the follow-up project progress.
