65Mn Steel Plate

Choose high-quality 65Mn Steel Plate, Sanhe Steel is your trusted supplier and manufacturer. The high carbon spring steel plate provided by our company has significantly improved its hardening ability and tensile strength by optimizing the manganese (Mn) content. The 65Mn Steel Plate produced by Sanhe Steel exhibits excellent comprehensive mechanical properties after heat treatment and is widely used in agricultural machinery and automotive industry components. It is an indispensable metal substrate in high load working environments. Whether you are looking for spot wholesale or customized special specifications, Sanhe Steel, as an experienced supplier, can ensure the safety of your materials with a rigorous quality control system.

Product Overview

65Mn belongs to the national standard high carbon spring steel, and its manganese content is usually between $0.90 \% \ sim 1.20 \%. By adding manganese element, this steel grade has better hardenability than ordinary 65 grade steel, and the surface decarburization tendency is also smaller.

Product Details Introduction

✱Composition characteristics: The high carbon content ensures the high hardness of the material after quenching, while the strengthening effect of manganese element endows it with good tempering stability.

✱Physical properties: It has a very high fatigue limit and can withstand multiple repeated loads without permanent deformation.

✱Surface quality: The steel plates supplied by Sanhe Steel have high surface flatness, no obvious cracks or oxide scales, which facilitates subsequent precision cutting and forming.

Product application areas

The application range of 65Mn Steel Plate is extremely wide, mainly including:

1. Hardware tools: circular saw blades, manual saws, paint scrapers, mud boards.

2. Automotive manufacturing: clutch plates, shock absorber springs, retaining springs, washers.

3. Agricultural machinery: rotary tiller blades, harrows, plows.4. Mining equipment: vibrating screen mesh, wear-resistant lining plate.

Core advantages of the product

✱Excellent resilience: It can quickly restore its original state after deformation under stress, making it an ideal material for manufacturing various elastic components.

✱Excellent machinability: In the annealed state, the material is easy to punch, cut, and machine.

✱High cost-effectiveness: Compared to alloy spring steel (such as 60Si2Mn), 65Mn Steel Plate has a more significant cost advantage while providing similar hardness performance.

Product usage precautions

1. Risk of quenching cracking: 65Mn is sensitive to overheating, and the heating temperature and holding time should be strictly controlled during quenching. It is recommended to use oil quenching to reduce deformation and cracking.

2. Rust prevention management: Due to its high carbon content, it is prone to rusting in humid environments. When storing, it is necessary to keep it dry and apply rust prevention oil.

3. Welding restrictions: This material is not recommended for welding structural components. If welding is necessary, preheating and post weld stress relief annealing are required.

FAQ

Q: What is the difference between 65Mn and 60Si2Mn?

A: 65Mn is more affordable and has sufficient hardness, but its toughness and hardenability are slightly inferior to 60Si2Mn. For ordinary mechanical springs and tools, 65Mn Steel Plate is a more cost-effective choice.

Q: Does Sanhe Steel provide cutting and processing services?

A: Yes, it is. We have high-power laser cutting and CNC cutting equipment, which can provide refined part processing according to your drawings, reducing your raw material loss.

Q: How to ensure the uniformity of hardness of steel plates?

A: The 65Mn Steel Plates provided by our company have undergone standardized heat treatment processes and come with original material certification (MTC) to ensure that the hardness deviation of each plate is controlled within a very small range.
