What are the effects of phosphorus in a573 grade 65 steel and a572 grade 65 steel differences

The company has allocated special environmental protection facilities for all a573 grade 65 steel and a572 grade 65 steel differences pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, a573 grade 65 steel and a572 grade 65 steel differences steel mill scale, environmental protection dust has reached 100%.

10CrMo9-10 steel plate is a kind of European standard pressure vessel steel plate, which is heat-resistant and high-pressure resistant boiler steel plate, belonging to alloy pressure vessel steel plate; 10CrMo9-10 steel plate is mainly used for power station boiler drum and steam boiler equipment. The a573 grade 65 steel and a572 grade 65 steel differences delivery state of 10CrMo9-10 steel plate is usually normalizing + tempering.

Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate a573 grade 65 steel and a572 grade 65 steel differences has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, a573 grade 65 steel and a572 grade 65 steel differences, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.

ASTM a588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of a588 and expand its application range. Firstly, the alloy composition increases the a573 grade 65 steel and a572 grade 65 steel differences yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 a573 grade 65 steel and a572 grade 65 steel differences has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, a588 angle steel is widely used in bridge, building and other structural fields.
