q345r equivalent astm material refining

Our technical department plays important role in our professional communication with customers, especially those who have high technical requirements for steel materials and those who need complex further processing. Under such condition, our technician department can provide technical support in time, anylize customer design or make drawing according to customer needs rapidly, so that we can proceed smoothly. The profession of our team has won great praise of customers.

ASTM A285 steel can be made into a variety of steel product forms, such as steel plates, q345r equivalent astm material steel coils, and steel pipes. It has good welding ability and can be used for fusion welding required by pressure vessel equipment. Its maximum thickness is limited to q345r equivalent astm material 50mm to ensure its mechanical properties.

Laser cutting q345r equivalent astm material has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the q345r equivalent astm material cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.

20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, q345r equivalent astm material. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.

Steel transportation because of the special material of q345r equivalent astm material 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.

We are known as q345r equivalent astm material leading manufacturers, suppliers and exporters in the market all over the world. We engage in providing a wide range of plates which are accurately mass produced by using the best quality of parts which gives maximum durability and dependability. The most important thing to know as a potential customer of IRON&STEEL is that we q345r equivalent astm material stock, processing service, and distribute all of the popular grades of carbon steel plate, alloy steel, shipbuilding steel and boiler steel.
