認証済みサプライヤー Hot-rolled steel coils/plates are steels made by high-temperature heating and rolling. Its strength is not very high, but its plasticity and weldability are good. Hot rolling can improve the processing performance of metals and alloys, break the coarse grains in the as-cast state, heal cracks, reduce or eliminate casting defects, transform the as-cast structure into a deformed structure, and improve the processing performance of the alloy.

1. High Strength: HRC Steel has high comprehensive mechanical properties. It can be used in the construction of large machinery and engineering, and also as the raw material for large welded structural parts.
2. Good Toughness: HRC Steel has good toughness. After heat treatment, it can also be used to make many mechanical parts.
(1) Structural steel is one of the most important uses of hot-rolled coils, and is used in construction, machinery, automobiles, oil and gas and other industries.
(2) Deep-processing of hot-rolled thin coils with a thickness of ≤3.0mm into cold-rolled coil substrates, hot-rolled pickling sheets, and hot-rolled galvanized sheets.
(3) For the manufacture of hulls and decks of ocean-going, coastal and inland shipping ships.
(4) Manufacture of pressure vessels or other similar equipment in petroleum, chemical and other industries.
(5) For bridge and railway construction
(6) Steel for oil and natural gas transmission pipelines is also the main application field of hot-rolled coils.
