Do a good job of thought introduction based on people. Human based management is the most important link in standardizing employee behavior management. In daily behavior management, we should establish the central position of human and play an important role of human. Employees are not only the builders and exercisers of corporate culture, but also the executors of code of conduct. The code of conduct should be finally implemented into the thoughts and actions of employees.
Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. S355MC hot-rolled steel, Q420C steel has good mechanical properties and weldability, good cold and hot workability.
30CrMnSiA steel delivery status: S355MC hot-rolled steel, 30CrMnSiA steel shall be delivered in the state of heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment, and the delivery status shall be indicated in the contract. 30CrMnSiA steel has high strength, but it belongs to medium carbon quenched and tempered steel, with large hardenability, so its weldability is very poor. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. And can be used as grinding wheel shaft, gear and sprocket.
Since the beginning of this year, the global S355MC hot-rolled steel steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global S355MC hot-rolled steel steel tube industry will also suffer from the "flash collapse" of international oil prices in March.

The spot price of 300 series stainless steel market has been slightly lower, and the previous increase has been further digested. But after the price of 304 hot-rolled plate and 304 cold coil rose, the market bullish mood seems to be stirred again. However, the spot S355MC hot-rolled steel price did not increase with the period, but mainly based on stable shipment. In particular, the current price of 304 hot-rolled large plate futures is close to the spot price; in addition, the recent poor market transaction price increases slightly resistance.
