ASTM A283 carbon steel plate sheet flaw detection process

In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.

Good ASTM A283 carbon steel plate sheet welding performance: Linepipe assemble is usually in the wild environment with fierce conditions, welding performance is one basic requirement for wild welding work. Corrosion resistant: gas or fluid transmitted in ASTM A283 carbon steel plate sheet pipelines may contain corrosive elements-S. Good moldability: for cold roll forming process is taken place before welding, good moldablity is the key to good ductility and toughness of final product.

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 ASTM A283 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 ASTM A283 carbon steel plate sheet weathering steel is purified and the content of inclusions is greatly reduced.

Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. ASTM A283 carbon steel plate sheet, Q420C steel has good mechanical properties and weldability, good cold and hot workability.
