Delivery state of SA633 grade C carbon steel plate sheet

The company has allocated special environmental protection facilities for all SA633 grade C carbon steel plate sheet pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, SA633 grade C carbon steel plate sheet steel mill scale, environmental protection dust has reached 100%.

Hot-rolled SA633 grade C carbon steel plate sheet steel plate mill operates heavy plate cutting, galvanized steel plate, steel plate punching, hot-rolled steel plate manufacturing, spring steel plate, 35crmo steel plate, 40cr steel plate, Q345C steel plate, 12cr1mov alloy plate, 16mn steel plate, A573 grade 70 pressure vessel plate, 15crmo alloy Steel plate, A516 grade 70 boiler plate, bridge structure steel plate, SA633 grade C carbon steel plate sheet corrosion-resistant steel plate, composite steel plate, pipeline steel plates, oil tank steel and alloy steel plate.

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. SA633 grade C carbon steel plate sheet, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

During the construction of hot-dip SA633 grade C carbon steel plate sheet galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the SA633 grade C carbon steel plate sheet construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of SA633 grade C carbon steel plate sheet, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).
