A573Gr70 plate technical conditions: the chemical composition and mechanical properties of A573Gr70 steel are produced in line with ASTM A573. When ordering, additional impact, flaw detection, z direction, composition control, performance requirements beyond the standard can be added. Available heat treatment processes of Q235B carbon steel plate sheet, A573Gr70 plate: hot rolling, controlled rolling, normalizing, tempering, quenching, normalizing + tempering. Our company supply flaw detection Z15-Z35 thickness direction performance.

Strip steel is a kind of steel plate with thin thickness, narrow width and long length. Strip steel can be made of common carbon steel, carbon structural steel, spring steel, tool steel, stainless steel, etc. Strip steel has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. There are many kinds of strip steel, Q235B carbon steel plate sheet. Hot rolled steel strip is mainly used for cold-rolled billets, cold-formed steel billets, welded steel pipe billets, manufacture of bicycles and small hardware products.

We do sand blasting and shop primer for various Q235B carbon steel plate sheet steel plates such as carbon steel plates, high strength low alloy steel plates, shipbuilding steel plates, etc. before delivery, so as to protect the steel plates from going rust during transportation. Our sand blasting standard is SA2.5, and shop primer Q235B carbon steel plate sheet thickness is 20μm or so. Our shop primer has been certified by ABS, LR, BV etc. authorities.

Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. Q235B carbon steel plate sheet, Q420C steel has good mechanical properties and weldability, good cold and hot workability.
