Buy & Import M2 W6Mo5Cr4V2 1.3343 High Speed Steel from Dongguan Otai Special Steel Co Ltd - China Wholesale Supply

M2 High Speed Steel, designated as W6Mo5Cr4V2 or DIN 1.3343, is a molybdenum-type tool steel widely used in the manufacture of cutting tools, drill bits, taps, and reamers for CNC and precision machining. Its chemical composition includes approximately 6% tungsten, 5% molybdenum, 4% chromium, and 2% vanadium, providing exceptional wear resistance and red hardness at elevated temperatures. The material’s carbide homogeneity and high toughness make it a preferred choice for high-performance metalworking applications in industries such as automotive, aerospace, and precision engineering.

Otai Special Steel’s M2 grade is noted for its small carbide inhomogeneity, which enhances its suitability for applications involving shock loads and vibration, such as cold forging dies, precision molds, and metal cutting saw blades. However, the grade is prone to overheating during heat treatment, requiring strict control of quenching temperatures and protective measures to prevent cracking or distortion. Standard industry practice for M2 HSS includes annealing at 850 to 900°C, hardening at 1,200 to 1,230°C, and tempering at 540 to 600°C to achieve optimal hardness and toughness.

This high-speed steel is globally traded, with Otai Special Steel positioning itself as a main supplier and stockist in China. Buyers in the automotive and aerospace sectors source M2 HSS bars for cutting tools and molds, while precision engineering firms use it for applications requiring high wear resistance and durability. Importers should confirm the quality grade (e.g., E/e, D/d, C/c) and whether the material has undergone ultrasonic inspection, as indicated by SEP 1921-84 standards, to ensure it meets their specific requirements.

Frequently Asked Questions About M2 W6Mo5Cr4V2 1.3343 High Speed Steel from Dongguan Otai Special Steel Co Ltd
M2 HSS typically contains approximately 6% tungsten, 5% molybdenum, 4% chromium, and 2% vanadium, with the remainder being iron. This composition provides the material’s characteristic wear resistance and red hardness, which are critical for cutting tool applications.

Sourcing M2 W6Mo5Cr4V2 1.3343 High Speed Steel from Dongguan Otai Special Steel Co Ltd - China Import Guide

Before ordering M2 HSS, confirm the quality grade (E/e, D/d, or C/c) and whether the material has undergone ultrasonic inspection in accordance with SEP 1921-84 standards. Request test reports or certificates of conformity to verify the material’s chemical composition and mechanical properties, as these are critical for high-performance applications. Additionally, discuss the supplier’s heat treatment capabilities to ensure the material meets your specific hardness and toughness requirements.

For logistics, clarify lead times and shipping terms with Dongguan Otai Special Steel, as these details are not specified in the supplier’s profile. M2 HSS is typically shipped in bar form, and buyers should confirm packaging standards to prevent damage during transit. Discuss Incoterms such as FOB or CIF, and payment methods to ensure smooth customs clearance and delivery.

Upon receipt, conduct a visual inspection of the M2 HSS bars for surface defects or irregularities. Use a hardness tester to verify that the material meets the typical hardness range of 65 to 68 HRC. Request documentation such as material test reports (MTRs) to confirm the chemical composition and heat treatment process. For critical applications, consider third-party inspection to validate the material’s compliance with industry standards and your specific technical requirements.
