15Mo3 steel manufacturing method: adopt oxygen top blown converter method, 182 open hearth method or 3666 to smelt in 3769 electric furnace. After negotiation with the customer, other equivalent methods can also be adopted.15Mo3 steel is used for heating surface pipes, economizers, superheaters, reheaters, etc. of high-pressure boilers (working pressure is generally above 9.8MPa, working temperature is between 450 ℃ ~ 650 ℃).

Bridge steel Hardox 450 suppliers is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance. With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges. In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges.

As the thickness and hardness of increase, the tendency to crack at the cutting edge increases. In order to prevent the from cutting cracks, preheating should be carried out before cutting. Special attention should be paid to preheating to make the entire Hardox 450 suppliers interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole cannot be preheated, the partial preheating method can be used instead.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
