JIS carbon steel SM490A CS plate chemical composition and mechanical property

Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, JIS carbon steel SM490A CS plate included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.

Carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the JIS carbon steel SM490A CS plate steel, and generally does not add a lot of alloy elements, sometimes it is also called ordinary carbon steel. Carbon steel refers to iron carbon alloy with carbon content of WC less than 2%. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus. According to the content of phosphorus and sulfur, the carbon steel can be divided into ordinary carbon steel, high quality carbon JIS carbon steel SM490A CS plate steel, high quality steel and super quality steel.

Steel transportation because of the special material of JIS carbon steel SM490A CS plate steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.

Galvanized seamless steel pipes are widely used, and can be divided into low and medium pressure galvanized seamless steel pipes, high-pressure galvanized seamless steel pipes, and stainless steel galvanized seamless steel pipes according to different requirements. Steel pipe JIS carbon steel SM490A CS plate can be used for industrial pipes with different pressures such as water vapor, air, oil, and gas.
