hardox 400 material elongation Checkered Steel Plate

The ASTM A36 I beam has moderate tensile and yield strength because of its low carbon content and no other alloying elements. A36 steel beam HARDOX 400 material elongation is commonly used in construction and civil engineering because of its competitive low cost and good welding, forming and processing properties. The hot-dip galvanized carbon steel beam can effectively protect the steel from the corrosion of weather and environment. The amount of zinc HARDOX 400 material elongation plating can be customized according to your requirements.

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and HARDOX 400 material elongation heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported HARDOX 400 material elongation to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick HARDOX 400 material elongation steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

The final heat treatment of quenched and tempered alloy steel, HARDOX 400 material elongation is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
