SM490B carbon steel plate sheet wooden box as required

Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business SM490B carbon steel plate sheet department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and SM490B carbon steel plate sheet after-sales service department constitute the service customer network.

Pipeline steel SM490B carbon steel plate sheet refers to the hot rolled coil plate or wide thick plate used to transport oil, natural gas and other large-diameter welded steel pipes. In the process of using pipeline steel, it is required not only to have high compressive strength, but also to have high low temperature toughness and excellent welding performance. Pipeline steel plates are used to make oil and gas pipelines. The main SM490B carbon steel plate sheet pipeline steel grades are API 5L grade B, API 5L X42, API 5L X60, API 5L X65 and so on.

304 stainless steel plate products have strong corrosion resistance. For ordinary alkali solution and organic acid, inorganic acid has good corrosion resistance. This material SM490B carbon steel plate sheet is a high alloy steel, which can resist corrosion in air or chemical corrosive medium.

Now many manufacturers will use CNC equipment to complete the steel plate cutting processing, this processing method is also gradually increasing, but if you want to make the processing effect meet the specifications and standards, the control requirements of operation technology are also relatively high. Now there are many kinds of steel plate cutting, during the actual processing, it is necessary to select the appropriate processing method according to the cutting requirements of steel plate, so as to achieve the ideal processing effect for SM490B carbon steel plate sheet.

Chemical composition of Q420 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 Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. SM490B carbon steel plate sheet, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
