Structural astm a573 standard structural quality carbon steel plate grade main allpication

Material common grades: Q235B,Q345B, AB EH32, AB DH36, AB EH36, astm a573 standard structural quality carbon steel plate, CCS-A, CCS-B,CCSA, CCSB, CCS,CCSD, CCSE. Carbon structural steel plates and sheets are mainly used in the manufacturing of mechanical parts with complex shapes and high requirements for mechanical properties, but it is difficult to shape them by forging and pressing in the process, such as the gearbox shell of the automobile, the coupler and coupling of the locomotive and vehicle.

Sulfur is a very harmful element in {keyword steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of {keyword steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.

Titanium microalloying is an element of astm a573 standard structural quality carbon steel plate strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in astm a573 standard structural quality carbon steel plate tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
