Why 09CuPCrNi-A stel tensile strength is generally not heat treated

Hydrogen (H) is the most harmful element in general steel such as 09CuPCrNi-A stel tensile strength. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's 09CuPCrNi-A stel tensile strength steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole 09CuPCrNi-A stel tensile strength steel transportation industry.

The advantage of plasma cutting is that it can cut thin plates, stainless steel and non-ferrous metals, and the cutting speed is fast. The disadvantage of plasma cutting is that the incision will have a slope, and there will be noise when cutting. The advantages of water jet cutting are wide cutting range and environmental protection, but the disadvantages of water jet cutting are slow cutting speed and high energy consumption. Do you know what is the best cutting method for 09CuPCrNi-A stel tensile strength?
