ASTM A387 Grade 5 and ASTM A387 Grade 9 Steel plates astm a537 class 1 hardness have good corrosion and heat resistance for alloy element chromium and molybdenum, which is needed in sour oil gas industry.

We have a lot of advantages for astm a537 class 1 hardness steel plate processing. First, we have huge steel plate stock. That not only saves material preparation time, but also saves much transportation cost. Second, we have professional technical team, who can design drawing according to client requirements quickly. Or if clients have drawing, we can communicate and make it clear soon. Third, we have built special steel processing center. The professional and experienced work will make you more satisfied and at ease.

Hydrogen (H) is the most harmful element in general steel such as astm a537 class 1 hardness. 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.

GB standard wear resistant steel plates parameters: The standard for Chinese wear plates is GB/T 24186, which includes NM400, NM450, NM500, NM550, NM600 etc. steel grades. According to the standard, the NM400 plate thickness is no more than 80mm, and hardness is 370-430HBW. astm a537 class 1 hardness, NM450 plate thickness is no more than 80mm, and hardness is 420-480HBW. NM500 plate thickness is no more than 70mm, and hardness is 470HBW min. And NM600 plate thickness is no more than 60mm, and hardness is 570HBW min.
