Buy & Import Alloy Steel from Shenzhen NewAsia Special Steel Co., Ltd. - China Wholesale Supply

AISI 4340 alloy steel from Shenzhen NewAsia Special Steel Co., Ltd. is a low-alloy, high-strength material distinguished by its nickel, chromium, and molybdenum content. These alloying elements deliver exceptional hardenability, fatigue resistance, and tensile strength, making it suitable for heavy-duty mechanical applications. The grade can be heat treated to achieve strength levels exceeding 1,500 MPa while retaining ductility and impact resistance, a balance critical for large cross-sections.

This steel is typically supplied in the annealed or normalized condition, with a carbon content of 0.38-0.43%, manganese at 0.60-0.80%, and phosphorus and sulfur limited to 0.035% maximum each. Its microstructure can be fine-tuned through quenching and tempering to meet specific mechanical property targets. Industry-wide, AISI 4340 is recognized for its deep hardenability, with a typical Jominy end-quench distance of 12-15 mm for 50% martensite.

Primary buyers include manufacturers in aerospace, automotive, and heavy machinery sectors, where it is used for crankshafts, gears, and aircraft landing gear. Importers sourcing from China should confirm heat treatment records and ultrasonic testing reports, as these are standard for critical applications. The HS code 72284000 applies, facilitating customs classification for alloy steel in this grade.

Frequently Asked Questions About Alloy Steel from Shenzhen NewAsia Special Steel Co., Ltd.
AISI 4340 contains nickel, chromium, and molybdenum as its primary alloying elements. These elements enhance hardenability, tensile strength, and fatigue resistance, making the steel suitable for high-stress applications like crankshafts and aircraft components.

Sourcing Alloy Steel from Shenzhen NewAsia Special Steel Co., Ltd. - China Import Guide

Before ordering AISI 4340 from Shenzhen NewAsia Special Steel Co., Ltd., verify the heat treatment records and mechanical test reports. These documents confirm the steel meets the required tensile strength, hardness, and impact resistance for your application. Request third-party inspection certificates if the material will be used in safety-critical components.

Confirm the Incoterms, packaging standards, and lead times for bulk shipments. AISI 4340 is typically shipped in bundles or coils, and buyers should specify packaging requirements to prevent damage during transit. FOB Shenzhen is a common Incoterm for steel exports from China, but CIF options may be available for larger orders.

Quality checks should include ultrasonic testing for internal defects and dimensional verification for plates or bars. Request a mill test certificate to ensure the chemical composition and mechanical properties align with AISI 4340 standards. For critical applications, consider arranging a pre-shipment inspection by a recognized agency like SGS or Bureau Veritas.
