Abstract
The invention discloses steel with the good welding performance. The steel is made from, by weight, less than or equal to 0.12% of carbon, 0.25%-0.75% of silicon, 0.4%-0.7% of manganese, less than or equal to 0.018% of phosphorus, 1.9%-2.6% of chrome, less than or equal to 0.018% of sulfur and the balance iron and impurities. The steel types comprise hot rolled sheet steel, leveled hot rolled coil steel and longitudinally-cut tape steel, the hot rolled sheet steel or the leveled hot rolled coil steel or the longitudinally-cut tape steel is taken as a raw material to be coiled by a coiling machine to obtain hair straightening steel coils, and then the hair straightening steel coils are subjected to head cutting, tail cutting, edge cutting, straightening and leveling. In this way, the steel with the good welding performance has the advantages that a method for achieving welding by adopting the steel is simple, the later welding process steps can be effectively decreased, the quality of welding products can be guaranteed, and the fracture and damage phenomena cannot be generated even if the steel is not used for a long time.
Description
Technical field
The present invention relates to Steel material field, particularly relate to a kind of steel with good welds performance.
Background technology
Steel is a kind of iron-carbon alloy.In steel in addition to mainly containing ferrum and carbon, possibly together with the multiple element such as phosphorus, sulfur, these elements have corresponding functional characteristic in steel.Phosphorus is harmful element, can reduce plasticity and the toughness of steel, cold brittleness occurs, and the intensity of steel can be made to significantly improve, and improves atmospheric corrosion stability simultaneously, and content should be limited in less than 0.05%.Generally sulfur is harmful element, makes steel red brittleness big, and content is limited in less than 0.05%, but the sulfur content of automatic steel is high, up to 0.08% ~ 0.40%.Existing steel welding performance is bad, uses meeting to be restricted, and is also susceptible to damage after using.
