Weathering steel is mainly used for steel structures exposed to the atmosphere for a long time, such as railways, vehicles, bridges, towers, photovoltaics, and high-speed projects. It S420MC steel for car body is used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive medium in chemical petroleum equipment.

The A283 C mild steel plate comes from the carbon steel which has a low carbon alloy. The mild steel plate/carbon steel plate is a combination of a low amount of chromium, and molybdenum with low carbon as well. Because of the low carbon alloy, it is more weldable, ductile rather than the carbon steel. The mild steel plate S420MC steel for car body is created magnetic and has a high amount of ferrite and iron. Mild steel has various characteristics like affordability, easy to weld, machinability.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and S420MC steel for car body pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.

The yield strength of S420MC steel for car body, Q235 steel plate decreases with the increase of thickness. Q235 steel plate thickness≤16mm, yield strength is 235MPA; 16mm < Q235 steel plate thickness≤40mm, yield strength is 225MPA; 40mm < Q235 steel plate thickness≤60mm, yield strength is 215MPA; 60mm < Q235 steel plate thickness≤100mm, yield strength is 205MPA; 100mm < Q235 steel plate thickness≤150mm, yield strength is 195MPA; 150mm < Q235 steel plate thickness≤200mm, yield strength is 185MPA.
