a242 type 1 weather resistant steel u channel Material Specification

EN10025-2 S235J2 steel is equivalent to our Chinese teel grade Q235D. They are both done low temperature impact test at -20℃. Sometimes S235J2 would be used to built containers which can bear low temperature sea water. a242 type 1 weather resistant steel u channel, S235J2+N steel plate, following a rolling process within a certain temperature range, producing a material in a condition equivalent to that obtained after normalization. With the result that the specified mechanical properties values are conserved even after normalization treatment.

In the past, a242 type 1 weather resistant steel u channel, NM360 wear-resistant steel plates generally do not add tungsten. However, after adding the alloying element tungsten, the carbides distributed along the grain boundaries are greatly reduced, the acicular carbides in the crystal disappear, and there are a large number of granular carbides in the crystal. Tungsten reduces the precipitation of carbides and is spherically dispersed in the austenite crystals, which is beneficial to improve the strength and toughness of the NM360 wear-resistant steel plate.

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the a242 type 1 weather resistant steel u channel steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the a242 type 1 weather resistant steel u channel steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent a242 type 1 weather resistant steel u channel products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the a242 type 1 weather resistant steel u channel technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
