High tensile strength ASTM A633 carbon steel plate sheet with MTC certificate

Our company has the ability to produce all kinds of steel structure parts. At the same time, we can design drawings according to the requirements of customers, and process according to the drawings. ASTM A633 carbon steel plate sheet Heat treatment services - such as annealing, normalizing, quenching, tempering, quenching and tempering, solution treatment, etc. We can also heat treat according to customer's ASTM A633 carbon steel plate sheet requirements.

ASTM A633 carbon steel plate sheet, 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.

The company has an annual spot inventory of 20,000 tons, and its own 20,000 square meter indoor warehouse, with normalizing container plates, API5L Gr.B wide and thick steel for oil and gas pipeline, extra wide and extra thick low alloy plates, ASTM A633 carbon steel plate sheet, chromium molybdenum steel, high strength plates, bridge plates, weathering steel, and excellent carbon Steel, military steel, etc. It can cut squares, discs, door frames, flanges, special-shaped parts, drilling, beveling, etc.

Hyundai Steel Co. has no plans to cut production further despite weak steel demand due to the coronavirus pandemic, the company's president said. Earlier this year, South Korea's second largest steelmaker reduced its ASTM A633 carbon steel plate sheet annual production of hot rolled coils from 1 million tons previously to 700 thousand tons per year for EAFs. A turnaround is expected after the third quarter of this year.
