All have low carbon, smooth surfaces, and good weldability. Used in automotive, appliances, and metalworking—valued for precision, workability, and consistent quality across varying fabrication needs.

4135, 4140, 4145 are SAE/AISI 4000-series alloy steels, primarily alloyed with chromium and molybdenum. 4140 is the most common, offering balanced strength, toughness, and hardenability. 4135 has slightly lower carbon, enhancing weldability. 4145, with higher carbon, boasts greater strength. All excel in heat treatment, used in shafts, gears, and structural parts requiring durability under high stress.

SS400, SS490, SS540 are JIS standard cold-rolled steel coils, graded by strength. SS400 (tensile 400-510 MPa) offers basic strength, used in general structures. SS490 (tensile 490-610 MPa) provides higher strength for medium-load parts like machinery components. SS540 (tensile ≥540 MPa) is high-strength, suited for heavy-duty applications. All have good weldability and formability, with cold-rolled precision. Widely applied in construction, automotive, and engineering, balancing performance and versatility across load requirements.

A514 carbon steel coil is a high-strength, quenched-and-tempered alloy steel meeting ASTM standards, with a minimum yield strength of 690 MPa. It contains alloys like chromium, molybdenum, and nickel, enhancing toughness and weldability. Ideal for heavy-duty applications—construction machinery, crane booms, and structural components under high stress. Its high tensile strength (760–965 MPa) and resistance to impact make it reliable in demanding environments, balancing strength with workability for critical load-bearing uses.

A387 is a chromium-molybdenum alloy steel coil, meeting ASTM standards for high-temperature pressure vessel service.
