QStE340TM automobile steel plate specification and properties

As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.

QStE340TM automobile steel plate Steel Standard: API 5CT Dimension range for casing and tubing: Outside diameter (26.67 to 114.30 mm); wall thickness(2.87 to 9.65 mm). Delivery state: Surface anti-corrosive treatment: bared, oiled, color paint, 3LPE; Tube and casing pipes ends: no swaging, threads and flanges. QStE340TM automobile steel plate Tubes testing: All tubing and casing pipes has passed ISO9001:2000 assessment and the API 5CT certification.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This QStE340TM automobile steel plate production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate QStE340TM automobile steel plate size.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for QStE340TM automobile steel plate, 42CrMo steel is quenching and tempering.

Steel transportation because of the special material of QStE340TM automobile steel 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.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our QStE340TM automobile steel plate products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
