Galvanized sheet metal S550QL steel from factory

Some S550QL steel, low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but also in some cases take appropriate precautions and even be exposed to the atmosphere without coating. Elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel, and molybdenum. The excellent atmospheric corrosion resistance has led to the formation of new concepts for structural design of buildings, bridges, and other structures.

40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel S550QL steel is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

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 S550QL 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.
