ASTM A387 Grade 5 and ASTM A387 Grade 9 Steel plates ASTM A 283 C, A 570 Gr. 33 carbon steel have good corrosion and heat resistance for alloy element chromium and molybdenum, which is needed in sour oil gas industry.
The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of ASTM A 283 C, A 570 Gr. 33 carbon steel structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.
