SA516 70 grade has the highest tensile and yield strength range due to the highest carbon content (up to 0.28%). For high-grade JIS G3114 hot-rolled plate grade SMA490BW steel plates such as SA516 70 grade, especially thick steel plates need to be preheated during arc welding.
If a destructive accident occurs during the use of the boiler, it will cause serious losses. Therefore, other than some common strengths with JIS G3114 hot-rolled plate grade SMA490BW, the boiler steel plate must have good physical properties, mechanical properties and workability, and be strictly specified in the technical terms of the material standard to meet its safety in use. High temperature (above creep temperature) boiler steel plates are generally low-alloy heat-resistant steels, such as chromium molybdenum steel, chromium molybdenum vanadium steel, chromium molybdenum tungsten steel, etc.
Hydrogen (H) is the most harmful element in general steel such as JIS G3114 hot-rolled plate grade SMA490BW. 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.
