Based on the main A709 Gr 50 bridge steel plate business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel A709 Gr 50 bridge steel plate products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
ASTM A633 standard covers four grades A, C, D, and E normalized high-strength low-alloy structural steel plates for welded, riveted, or bolted construction. A709 Gr 50 bridge steel plate, A633 Grade A structural steel provides a minimum yield point of 42 ksi [290 MPa] in thicknesses through 4 in. [100 mm], inclusive. Grades C and D provide a minimum yield point of 50 ksi [345 MPa] in thicknesses up to 2.50 in. [65 mm], inclusive and 46.0 ksi [315 MPa] in thicknesses over 2.50 in. to 4.0 in. [65 to 100 mm], inclusive.
S235JR steel plate is one mainly of Carbon and low alloy steel, S235JR steel plate is a type of steel sheet under EN standard which is used to build ship, bridge, belongs to high strength sheet. EN10025-2 S235JR is equivalent to DIN:ST37-2,JIS:SS400,ASTM:A283C, GB Q235B and UNI:FE360B.
Semi-endless rolling technology has three advantages: the A709 Gr 50 bridge steel plate product's limit thickness and limit width specification range has been significantly expanded. The thinnest thickness of SPHC steel has been expanded from 1.0 mm to 0.78 mm, and the limit specification product width has been expanded from 1100 mm to 1300 mm; The thinnest thickness of Q235B steel has been expanded from 1.2 mm to 1.0 mm, and the width range of the limit specification products has also been further expanded.
A387 Gr 91 Cl 1 alloy steel is an option for use in sour service environments. The material has good weldability and with its heat resistant qualities, the material is a highly versatile steel which can be used in numerous applications. A387 Gr 91 Cl 1 steel tensile requirements Tensile strength, ksi [MPA]: 85 to 110 [585 to 760] Yield strength, min, ksi [MPa]/(0.2% offset): 60 [415] Elongation in 2 in. [50mm], min, %: 18
