Hot-rolled coil is a steel strip coil that is continuously produced from steel billets after being heated at high temperatures and then passed through a rolling mill. It has the characteristics of high strength, good toughness and easy processing, and is widely used in construction, automobiles, machinery and other fields.

ASTM A387 steel coil is chromium-molybdenum steel for pressure vessels for elevated temperature service. ASTM A387 steel coil include ASTM A387 Grade 5, Grade 9, Grade 11, Grade 12, Grade 22. Each A387 grade is divided into 2 class: class 1 and class 2.

ASTM A514 steel (also known as T1) grades incloud A, B, E, F, H, P, Q & S. This steel coil has a high yield strength and good weldability. ASTM A514 steel coil is quenched and tempered carbon-alloy steel. It is typically used when abrasion resistance and high-impact properties are required.

Our Q195 Carbon Steel Plate (0.15-80mm thickness, custom sizes) meets GB/ASTM standards, offering high ductility and easy processing for roof panels, brackets and pipes, with SGS inspection and seaworthy packaging.

High carbon steel plate is a steel plate with a higher carbon content, usually between 0.60% and 1.70%. It is mainly used to manufacture high-strength and high-wear-resistant tools and parts.

ASTM A573/A573M grades include 58, 65 and 70. Steel plates are suitable for structural carbon-manganese-silicon steel plates with three tensile strength ranges. ASTM A573/A573M steel plates are mainly used to improve notch toughness at room temperature.

ASTM A515 carbon-silicon steel plates primarily for intermediate- and higher-temperature service in welded boilers and other pressure vessels. Plates are available in three grades having different strength levels: Grades 60, 65, 70, 415, 450, and 485.

Q215 is a type of carbon structural steel that complies with the Chinese national standard GB/T 700-2006. The "Q" in its name stands for yield strength, while "215" indicates a minimum yield strength of 215 MPa, which decreases gradually as the thickness of the steel increases. Its chemical composition is primarily low carbon (carbon content ≤0.15%), with sulfur and phosphorus content controlled according to grades A and B. It possesses good plasticity, toughness, and weldability, and is typically used directly in the hot-rolled or normalized state.

Q195 carbon steel pipe is a welded steel pipe made of carbon structural steel. Its yield strength is 195MPa (thickness ≤16mm), tensile strength ranges from 315 to 430MPa, and elongation is ≥32% (thickness or diameter >16mm)
