What grade is KA40 ship steel plate sheet?

What grade is KA40 ship steel plate sheet?

DIN 34CrMo4 steel Strength, high hardenability, toughness, and quenching small deformation, high strength and creep rupture strength at high temperatures. Requirements for the manufacture of higher intensity than the 35CrMo steel KA40 ship steel plate sheet and tempered forging greater cross-section, such as a large locomotive traction gears, supercharger drive gear, pressure vessels, gear, rear axle, greatly affected by load and spring clip link It can also be used to 2000m deep oil drill pipe joints and fishing tools, and KA40 ship steel plate sheet can be used bending machine mold, etc.

KA40 ship steel plate sheet smelting method
The smelting process of electric furnace + external refining and vacuum degassing can be used for secondary electroslag remelting smelting. The steel plate should be intrinsically fine-grained steel, belonging to the 1.25Cr-0.5Mo series of pearlite heat-resistant steel, with good high-temperature strength, oxidation resistance, and sulfide corrosion resistance below 500°C. It is widely used in coal chemical industry and petroleum High temperature and high pressure vessel installation in the chemical industry.

From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. KA40 ship steel plate sheet, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.

The yield rate is a comprehensive technical and economic index in the production of medium and heavy plates such as KA40 ship steel plate sheet. Increasing the yield rate can not only reduce the loss of metal, but it is also vital to the economic benefits of the steel enterprise. The influencing factors of the yield of medium and heavy plates are various, for example, the variety structure, negative deviation rolling level, plate shape control level, cutting loss, rolling waste and burning loss, etc.
