ASTM A335 boiler steel pipe is a kind of martensite high alloy steel with high temperature and high pressure resistance. A335 P5 P11 P12 P22 seamless alloy steel pipes are generally applied in the high temperature and high pressure main pipes of power plant.

When cutting parts with gas, the verticality of the thickness of P235GH steel section of the parts should not be greater than 15% of the thickness of the parts. There can be rounded corners at the sharp corners, but the radius should not be greater than 2.5mm. The concave and convex points at the edges of the parts should not exceed 1.5mm. If the parts are cut by hand, the verticality of the section shall not be greater than 15% of the thickness of the parts. If the parts are cut underwater, the verticality of the section should not be greater than 10% of the thickness of the parts.

Classification of hot rolled steel plate: hot rolled steel plate can be divided into thickness of p235gh steel ordinary thin steel plate, pickling thin steel plate, roofing plate, oil barrel plate, pattern steel plate, shipbuilding steel plate and automobile steel plate according to its use.

The European Iron and Steel Industry Union (Eurofer) has sent a letter to the president of the European Commission, asking the Commission to review the existing trade safeguard measures immediately, proposing to reduce the steel import quota by 75% within six months to help the European steel industry cope with the current difficult situation; For imported steel exceeding the quota, the tariff rate can be reduced to less than 25%. Europe has also proposed restrictions on thickness of p235gh steel and so on steel imports related to crisis and safety.
