A514 grade E quenched and tempered steel,For the estimation in April and the second quarter, the estimation on March 16 is still valid, but the decrease in April is 10% higher than the neutral prediction. It is a conservative estimation based on 10% for the high probability event. In the second quarter, the output of overseas pig iron will be reduced by 11.67 million tons, affecting the demand for iron ore of about 1.84 million tons; in the first half of the year, the output will be reduced by 18.899 million tons, affecting the demand for iron ore of 32.13 million tons.A514 grade E quenched and tempered steel
After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with usA514 grade E quenched and tempered steel
Low alloy steel Q345E angle steel bar can be composed of various stress-bearing components according to the different needs of the structure, and can also be used as a connecting piece between the components. Q345E angle steel is widely used in various building structures and engineering structures, such as house beams, bridges, power transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.
In 2016. Our company offer 1200 tons API 5L GR.B hot rolled coil to Bangladesh——100 tons for 3.9*625mm, and 1100 tons for 7*683mm. It is one tender project, we get the tender at the end of 2015, and arrange the production in 2016. They required the tolerance of thickness is +0.1/-0.2mm, and width tolerance is +/-0.5mm, which is a very high requirement for coil tolerance, but our mill handling this very well. and our Q/C department witness all of the process.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel It has low strength, good toughness, plasticity and good weldability Chemical composition of 20 # round steel bar: C: 017 ~ 023, Si: 017 ~ 037, Mn: 035 ~ 065, S: ≤0035, P: ≤0035, Cr: ≤025, Ni: ≤030, Cu: ≤025 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min 25%,A514 grade E quenched and tempered steel.
The microstructure of the quenched and tempered alloy steel after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.
