There are four main advantages of NC cutting for marine grade AH40 steel plate

Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of marine grade AH40 steel plate service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.

Carbon steel marine grade AH40 steel plate is an iron carbon alloy with carbon content less than 2.11% and a small amount of silicon, manganese, sulfur, phosphorus and other impurities. Carbon steel inevitably contains some impurity elements during smelting, which has a great influence on the performance and quality of steel, so it should be controlled. The quality of carbon steel is mainly measured by the content of sulfur and phosphorus. The lower the marine grade AH40 steel plate content of sulfur and phosphorus, the better the quality of carbon steel.

15CrMo alloy steel plate is pearlite structure heat-resistant steel, which has high heat strength (δb≥440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of steel marine grade AH40 steel plate is obvious and the weldability is poor. 15crmo alloy steel plate is mainly used in petroleum, petrochemical, high-pressure boilers, etc.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick marine grade AH40 steel plate steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

The high strength marine grade AH40 steel plate low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of marine grade AH40 steel plate ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
