Q460D carbon steel plate sheet rolling points

S355J0 steel is a low alloy structural steel. We can supply S355J0 structural steel plates up to 400mm, with a minimum yield strength 355MPa when plate thickness less than 16mm, min. yield strength 345MPa when plate thickness range 16mm to 40mm. Without any special rolling or heat treatment for S355J0 steel plate and sheet, Q460D carbon steel plate sheet, the abbreviated designation of this delivery condition shall be AR (As rolled).

Specification range of available steel Q460D carbon steel plate sheet: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates Q460D carbon steel plate sheet can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the Q460D carbon steel plate sheet steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the Q460D carbon steel plate sheet weathering steel is purified and the content of inclusions is greatly reduced.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate Q460D carbon steel plate sheet EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the Q460D carbon steel plate sheet principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
