AISI 1045 steel is medium carbon steel with high quality and strength. Because of the bad hardenability, it always is used in the normalizing condition. If it needs higher mechanical property, that it should be thermal refining. Take from Songshun Steel 1045 Steel Chemical Composition Carbon (C): 0.43-0.50 Silicon (Si): 0.17-0.37 Manganese (Mn): 0.60-0.90 Sulfur (S): ≤0.0050 Phosphorus (P): ≤0.040 Chromium (Cr): ≤0.25 Nickel (Ni): ≤0.25 1045 Steel Mechanical Property intensity of tension: ≥600(61) yield strength: ≥355(36) percentage elongation: ≥16 reduction of cross-sectional area: ≥40 Impact energy: ≥39 Impact toughness: ≥49 hardness: ≤229HB( without heat treatment); ≤197HB( after annealing) In the market, the quantity of hot rolling 1045 steel is the biggest one. Its cold-plastic nature is poor. And It has good strength and machinability. A certain degree of toughness, plasticity and wear resistance can be obtained after appropriate heat treatment. Suitable ...

In the steel industry, so many complicated things you need to worry about. Such as the part of steel supply, you need to figure out what steel grade is your need, what is the right specification for me and etc. So we need to consider all the stuff about it to make it in the right way. Take from Songshun Steel Before The Supply First of all, you need to confirm the quantity of steel that you need. You absolutely do not want the steel material have left after a project finished. That will bother you. You need to solve the problems of steel place, care and etc. If you want to take it back to the steel supplier, that is impossible and ridiculous. Because of the cost of transport and etc are so big, that is not a good choice. By the way, some steel material almost was made at the base of your needs, that means the steel material is not suitable for other people. Combine all such things, the thing of confirming really quantity of steel is very big. That will be good for you and sup...

Take from Songshun Steel At the background of Chinese take the action to limit the production of steel in 2019, the steel price also will be affected. The recent time, the price of screw thread steel is raised. And it is over 40000 Yuan in China. And many steel companies say, even at the time of lower demand, but the situation of it is good. Many people are optimistic in July. For the trends of the screw thread steel price in recent time, many people have own thought. All the people think the main reason for the price decreasing is the steel production limit. This action will continue to the end of July. So steel price will keep decrease in July. As the steel production limit going, the production of steel will keep down. The price of steel will go up then slow down. As the profits of the steel factory decrease, the impact from the steel production limit will increase. In addition, in the latest report of Tangshan City Air Pollution Prevention and Control Intensified Manag...
