Based on the main S700MC steel for large truss truck boom business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and 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 S700MC steel for large truss truck boom products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

The market demand affects the S700MC steel for large truss truck boom, stainless steel price: if the downstream industries such as infrastructure, real estate and hardware products have strong production demand and large procurement volume, it will naturally affect the price of stainless steel. And these large macro data will be disclosed by related statistical departments, therefore, stainless steel purchasers need to understand the macro economic data. Secondly, the international market trade environment and policies among countries will also have a certain impact on the import and export of stainless steel.

API 5L X70 steel plate/pipes, API 5L X70 steel plate/pipes, under API 5L standard, we can regard X70 steel plate/pipes as large diameter pipes. X70 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X70 steel with the demands in mechanical properties of the pipes followed the API specification for grade X70 (YS is 485MPa, TS is from 600-750 MPa).It is well known that a low carbon bainitic microstructure offers an excellent combination of strength and toughness.

S700MC steel for large truss truck boom, Q345B low alloy steel plate composition:
1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%;
2) Add manganese-based alloying elements;
3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel;
In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.

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 S700MC steel for large truss truck boom, 42CrMo steel is quenching and tempering.
