Heat Treated Steel Bar And Tube
HEAT TREATED STEEL BAR AND TUBE
Heat treated steel bar is produced by heating and cooling in different temperature based on the steel grades to improve the steel bar mechanical properties or machinability for various industrial applications. Heat treated steel bar includes annealed steel bars, Normalized Steel Bar, quenched and temper qt steel bar.
Annealed Steel Bar has better ductility and lower hardness, which can be easier to be machined. The annealing processing is usually widely used for steel grade with higher carbon content above 0.5%. However, some low carbon steel also requires to do annealing for special usage such as 20CrMnTi gear steel. For some special material such as 20CrMnTi gear steel and GCr15 such bearing steel, spheroidizing annealing is often required.
Normalized steel bar sometime is also one kind of annealing processing. It mainly changes the grain to remove the impurities in steel and improves the strength and hardness. For some hot rolled steel bars, to keep the basic mechanical properties, normalizing is often used.
Quenching and Tempering, abbreviated as Q&T is a king of processing that strengthen or harden steel bars by heating the materials and then cooling in water, oil or other liquid medium, that rapidly the change from austenite to perlite to get the proper properties for various usage. The quenched & tempered steel bar materials are usually with carbon from 0.30% - 0.60%, it is widely used as merchant bars in components of various machines.
Our advantages on producing heat treated steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of Cold Drawn Steel Bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty

"Our next stage of our development goal is to help Chinese companies and China's nuclear power industry go global through our cooperation. This beneficial cooperation with Guangdong Province will accelerate the pace of the entire Chinese nuclear power industry going global. "Ma Shilu said.
At present, Guangdong has a total of 6 nuclear power plants that are in operation or under construction in Daya Bay, Taishan and other regions. The EDF Group has already cooperated with China National Nuclear Power Group, China’s largest nuclear power company, and has maintained a very good cooperative relationship for a long time.
Ma Shilu said that I believe that the alliance between France Power and China Guangdong Nuclear Power Corp., two powerful companies, will have a very positive impact on the entire world and will also have a very positive effect on energy development and the use of nuclear power in Guangdong.
To achieve the goal of making China's nuclear power companies and the nuclear power industry go global, he believes that the most important issue at present is to bring China's nuclear energy quality and safety standards into line with the world.
"I think that the cooperation between Guangdong and China's nuclear power companies and foreign nuclear power companies will make this process of integration even earlier," said Ma Zhilu.
EDF is one of the world’s largest nuclear power operators and has 58 operating nuclear power plants worldwide. 
Strengthening Cooperation to Promote China's Nuclear Power to the World
Ma Shilu, senior executive vice president of the French Electricity Group, who attended the Guangdong International Economic Development Consultation Conference in Guangzhou, revealed on the 14th that he will strengthen cooperation with Chinese nuclear power companies to help China's nuclear power industry go global.
