The main use of хардокс 500 equivalent astm

хардокс 500 equivalent astm annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of хардокс 500 equivalent astm annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. хардокс 500 equivalent astm annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

High quality structural steel thick plate product хардокс 500 equivalent astm dimension(mm): 40*2300*12000, 50*1780*7000, 16*2300*12000, 50*2500*10120, 55*1800*11900, 25*2300*12000, 50*2500*10060, 60*2500*8400, 60*2100*10000, 80*1920*6000, 130*2200*10000, 140*2200*10000, 55*1800*11550, 110*2320*8100, 40*1900*7350, 150*2200*10000, 45*2200*9000, 60*2500*8300, 40*2300*12000, 90*2440*12400, 125*1920*5000.

At present, there is no obvious release of market demand, the terminal is basically purchased on demand, and the transaction volume is not obvious. However, the current market inventory resources of хардокс 500 equivalent astm are relatively small, business sales pressure is not big, coupled with cost support, so the willingness to stand out is strong. However, after the continuous rise in the early stage, the market's fear of heights has increased, and the operation is still dominated by shipment, and the space for хардокс 500 equivalent astm price rise is limited. Overall, it is expected that хардокс 500 equivalent astm prices will be strong tomorrow.

Chromium element (Cr element) can improve the strength and hardness of хардокс 500 equivalent astm, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
