Product Description

AISI 5140 Alloy Metal Sheet Price 20mm 34crmo6 Hot Rolled Carbon Steel Plate for Chemistry Industrial Use CNC Cutting Factory
Carbon steel plate sheet is a type of steel that contains less than 2.11 percent carbon and has not been deliberately mixed with metal elements. It is also known as carbon steel or carbon steel. In addition to carbon, it has a small amount of silicon,manganese, sulfur, phosphorus and other elements, the higher the carbon content, the better hardness and strength, but less plasticity.

Product Description

34CrMo6 Steel Plate
The grade you mentioned is officially 34CrNiMo6 (per European Standard EN 10083-3, material number: 1.6582), a high-strength quenched and tempered chromium-nickel-molybdenum alloy steel plate. It is often abbreviated as 34CrMo6 (omitting the Ni element).
1. Basic Information (Steel Plate)
Grade: 34CrNiMo6 (34CrMo6)
Standards: EN 10083-3, DIN 17200
Equivalent grades: AISI 4340 / 4337 (US standard), GB 34Cr1Ni1Mo (Chinese standard)
Product form: Hot rolled steel plate / Quenched & Tempered (+QT) steel plate
Key characteristics: Excellent hardenability, high strength and toughness, superior fatigue resistance, low-temperature impact resistance, and temper brittleness resistance. Ideal for heavy-section load-bearing components.

4. Common Heat Treatment
Quenching: 840-870ºC, oil quenching (continuous roller quenching for steel plates)
Tempering: 560-650ºC, air cooling (quenched and tempered for balanced strength and toughness)
Surface treatment: Nitriding (HV 650-850), Induction hardening (HRC 54+)
5. Typical Applications
Wind power industry: Gearbox plates, main shaft flanges, bearing housings
General machinery: Heavy-duty gears, thick-walled shafts, high-strength structural plates, high-pressure vessel components
Automotive industry: Thick plates for crankshafts & connecting rods, heavy-load chassis parts, gear blanks
Energy industry: Boiler drums, high-pressure heat exchangers, pressure-bearing equipment
6. Comparison with 34CrMo4 / 42CrMo4 Steel Plates
34CrNiMo6 (1.6582)Contains approx. 1.5% nickel, featuring outstanding low-temperature toughness and deep hardenability. Uniform mechanical performance for thick plates (over 50mm), with a higher cost.
34CrMo4 (1.7220)Nickel-free, cost-effective, with ordinary toughness and hardenability. Suitable for medium & thin plates and normal temperature working conditions.
42CrMo4 (1.7225)Higher carbon content for greater strength, but slightly lower toughness. Mainly used for wear-resistant parts and medium-section components.
