Operation of LR AH40 shipbuilding steel plates industry from January to December last year

The quenching and tempering treatment of LR AH40 shipbuilding steel plates steel plate: after quenching, the heat treatment method of high temperature tempering is called quenching and tempering treatment.High temperature tempering refers to tempering between 500℃ and 650℃.The properties and materials of steel can be greatly adjusted by tempering and tempering. Its strength, plasticity and toughness are good, and it LR AH40 shipbuilding steel plates has good comprehensive mechanical properties.

Titanium microalloying is an element of LR AH40 shipbuilding steel plates strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in LR AH40 shipbuilding steel plates tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to materials and properties. According to the different uses, it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, LR AH40 shipbuilding steel plates, welding gas cylinder and pressure vessel steel, pipeline steel, etc. We adhere to the tenet of "customer first, quality assurance and good reputation", and always provides high-quality products for our customers.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our LR AH40 shipbuilding steel plates products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
