The Main Features of 42CrMo Alloy Steel


The performance of 42CrMo Alloy Steel is close to 35CrMo. 42CrMo Alloy Steel Plate's strength and hardenability are better than 35CrMo due to the increase in carbon and chromium content. 42CrMo Alloy Steel Plate has a high fatigue strength and resistance to multiple impact capacity after quenched and tempered. Besides, its low temperature impact toughness is good, and it is no obvious tempering brittleness.

What are the Qualities of Hot Sale 316L Stainless Steel Plate

Grade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel.

Physical Properties of Type 316 Steels

• Density: 0.799g/cm³
• Electrical resistivity: 74 microhm-cm (20C)
• Specific Heat: 0.50 kJ/kg-K (0-100°C)
• Thermal conductivity: 16.2 W/m-k (100°C)
• Modulus of Elasticity (MPa): 193 x 10³ in tension
• Melting Range: 2500-2550°F (1371-1399°C)
