JIS G3106 SM520C steel equivalent astm The company is committed to the promotion of new technologies

Steel is an alloy of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements. In addition to iron, carbon content plays an important role in the mechanical properties of JIS G3106 SM520C steel equivalent astm and so on steel. Iron and steel is an important raw material for machinery, construction, hardware and other industries. As an important pillar industry, the development of iron and steel has a glorious period, in which Tangshan was once an important production base of China's iron and steel. This is closely related to its geographical location and energy advantages.

, Q690 steel is low alloy high strength steel. It belongs to the Chinese GB standard steel. Q690 steel is named after its yield strength value. Q is the abbreviation of yield strength, that is, the yield strength of Q690 steel is 690 MPa. Chemical composition of Q690 steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 1.00, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. The mechanical properties of Q690 steel are: yield strength ≥ 690 MPa, tensile strength 730-940 MPa, elongation after fracture ≥ 14%, impact energy 31J.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.

We supply more than 2,000 tons of high strength low alloy steel coils to support the construction of Iraq's thermal power equipment projects. As a "Belt and Road" construction project, the Iraqi thermal power generation project has high requirements on the quality of steel for power generation equipment. In particular, the flue gas baffle door sealing system of thermal power plants has extremely strict requirements on the composition, yield strength and tensile strength of steel. Our hot rolled low alloy steel coils have won the favor of customers for their excellent mechanical properties, standard sizes, and beautiful shapes.
