Manganese steel vs carbon plate
Manganese steel and ordinary steel belong to carbon structural steel and low alloy structural steel. The difference between manganese steel and EN 10025-6 high strength steel S620QL1 is different in compressive strength, strength and main purpose. In terms of compressive strength, the compressive strength of manganese steel is higher than that of ordinary steel plate. In terms of strength, the strength of manganese steel is also higher than that of carbon steel, and in terms of application, manganese steel plates have more prominent advantages due to the advantages of materials, so the application areas are more common."

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 EN 10025-6 high strength steel S620QL1 is obvious and the weldability is poor. 15crmo alloy steel plate is mainly used in petroleum, petrochemical, high-pressure boilers, etc.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than EN 10025-6 high strength steel S620QL1. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel EN 10025-6 high strength steel S620QL1 is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

EN 10025-6 high strength steel S620QL1, API 5L X52 steel with the thickness range is 1.2-40mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. API 5L X52 steel’s mechanical properties is the yield strength 300MPa, and the tensile strength 460MPa. To be specified in details: Maximum content for C≤0.28%, Mn≤1.4%, P≤0.030%, S is 0.030%, V+Nb+Ti≤0.15%, Copper maximum is 0.50%, nickel maximum 0.50%, chromium 0.50%, Molybdenum 0.15%.
