The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of A709 grade 50W low alloy steel sheet, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.
With the increase of temperature, the yield limit of A709 grade 50W low alloy steel sheet will decrease monotonically, but the tensile strength of A709 grade 50W low alloy steel sheet will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of A709 grade 50W low alloy steel sheet. Near the blue brittleness temperature, the A709 grade 50W low alloy steel sheet strength increases and the plasticity decreases. The elongation and section shrinkage of A709 grade 50W low alloy steel sheet increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
India's Ministry of A709 grade 50W low alloy steel sheet steel has extended the deadline for steel product certification from April 23 to three months as the Bureau of standards (BIS) has closed factories and laboratories due to the current blockade and travel ban. According to the order of the Ministry of Commerce, "the implementation date of the following Indian Standards is extended for three months after April 23, according to the notice of the order for A709 grade 50W low alloy steel sheet steel products 2000."
Our company is a specialized technical support and after-sales service organization - customer service center. At the same time, we have provided excellent technical A709 grade 50W low alloy steel sheet personnel and strong technical support for our company, and cultivated an excellent after-sales team for our company. Our company will appoint a full-time service manager to be responsible for the unified coordination of technical support and A709 grade 50W low alloy steel sheet after-sales service of the project.
Today, the domestic financial market generally recovered, boosting market confidence, the purchasing activity increased, and A709 grade 50W low alloy steel sheet prices rose. At present, the current steel production enthusiasm is high, A709 grade 50W low alloy steel sheet production continues to maintain a high level. At the same time, the market has certain expectations for the release of demand in the peak season, and A709 grade 50W low alloy steel sheet consumption is expected to improve in the later stage. Under the prosperous supply and demand, it is expected that the short-term A709 grade 50W low alloy steel sheet prices will be strong.
