About Dong Guan Hua Xing Long Molding Steel Co., Ltd. - Steel Bars Supplier in China

Located in China, Dong Guan Hua Xing Long Molding Steel Co., Ltd. lists five distinct steel product lines in its catalogue. The supplier’s portfolio includes high speed steel AISI M2, plast mould steel P20 (HS code 7228.80), cold‑work tool steel CR12/D3/DIN 1.2080 (HS code 7228.20), hot‑work tool steel H13 (HS code 7228.40), and cold‑work steel SKS3/DIN 1.2510/O1 (HS code 7228.20). Each entry is identified by its alloy designation and, where provided, the corresponding HS‑code that falls under Chapter 72 of the Harmonised System, which covers articles of steel. The catalogue reflects the supplier’s focus on tool‑making and mould‑making steel grades commonly used in precision engineering.

The five products are described using standard alloy names such as AISI M2, DIN 1.2311 for P20, and DIN 1.2344 for H13, indicating the chemical composition and heat‑treatment routes. The HS‑code families 7228.20, 7228.40 and 7228.80 signal that the goods are classified as cold‑work tool steel, hot‑work tool steel, and other alloy steel bars respectively. No additional product categories are listed, and the supplier does not disclose further manufacturing capacity or client references.

Product Range and Specialties of Dong Guan Hua Xing Long Molding Steel Co., Ltd.

The catalogue offers high speed steel M2, a cobalt‑free grade typically containing 0.85 % carbon, 4 % chromium, 5 % molybdenum and 6 % vanadium, supplied as round or square bars for cutting tools. Plast mould steel P20 is a pre‑hardened chromium‑molybdenum alloy (approximately 0.30 % C, 1 % Cr, 0.30 % Mo) used for injection moulds and commonly delivered in 5 t bundles. Cold‑work tool steel CR12/D3 (DIN 1.2080) is a high‑carbon, high‑chromium steel with typical hardness 58‑62 HRC, suitable for die‑cutting and stamping, while hot‑work steel H13 (DIN 1.2344) provides high hot‑hardness and thermal fatigue resistance for die‑casting applications. The cold‑work alloy SKS3/O1 (DIN 1.2510) offers good wear resistance for knives and punches, usually supplied in 10 mm to 40 mm diameters.

Industry standards for these grades include ASTM A681 for tool steels, EN 10277 for cold‑work, and JIS G4801 for hot‑work steels. Typical specifications reference chemical composition limits, hardness ranges, and tensile strength values, for example H13 often meets a minimum tensile strength of 900 MPa after heat treatment. Buyers can expect the steel to be delivered in standard steel pallets or wooden crates, with each pallet accommodating up to 2 t of material.

Trade and Export Information - Dong Guan Hua Xing Long Molding Steel Co., Ltd.

China is a leading exporter of tool steels, and shipments of HS‑code 7228.xx products regularly flow to automotive, aerospace, and general‑machinery manufacturers in Europe, North America, and Southeast Asia. The hot‑work grade H13 is especially demanded by die‑casting plants in Germany and the United States, while cold‑work grades such as P20 and O1 are common in injection‑moulding facilities in Japan and South Korea. Importers typically require compliance with ISO 9001 quality management, and product certification against ASTM A681 or EN 10277, depending on the destination market.

Customs classification under Chapter 72 means that the goods are subject to anti‑dumping duties in certain jurisdictions, and import licences may reference the specific HS‑code (e.g., 7228.20 for cold‑work tool steel). Standard packaging includes 5 t or 10 t bulk bundles wrapped in stretch film and palletised, with markings for heat‑treatment condition. Common Incoterms used by Chinese steel exporters are FOB Shanghai or CIF Hamburg, allowing buyers to arrange freight and insurance according to their logistics strategy.

Sourcing from Dong Guan Hua Xing Long Molding Steel Co., Ltd. - Buyer Guidance

When sourcing from Dong Guan Hua Xing Long Molding Steel, request a Mill Test Certificate that details chemical analysis, heat‑treatment parameters and compliance with the relevant ASTM or EN standard. Buyers should also ask for a hardness report (Rockwell C) and, where applicable, a tensile test sheet to verify that the steel meets the stated grade specifications.

Typical minimum order quantities for tool‑steel bars range from 1 metric tonne per grade, with lead times of four to six weeks for heat‑treated grades such as H13 and P20. Verify that the supplier can provide REACH‑compliant documentation for hazardous substance content, and confirm packaging dimensions to ensure container loading efficiency, usually 20‑ft or 40‑ft containers with standard steel pallets.

What steel grades does Dong Guan Hua Xing Long Molding Steel export?

The supplier lists high speed steel M2, plast mould steel P20 (HS 7228.80), cold‑work tool steel CR12/D3 (HS 7228.20), hot‑work tool steel H13 (HS 7228.40), and cold‑work steel SKS3/O1 (HS 7228.20).

Which HS codes are associated with the listed products?

P20 is classified under 7228.80, CR12/D3 and SKS3/O1 under 7228.20, and H13 under 7228.40. The high speed steel M2 does not have a specific HS code in the provided data.

What certifications should a buyer request for these tool steels?

Buyers should request a Mill Test Certificate, and verify compliance with ASTM A681 or EN 10277, as well as ISO 9001 quality‑management certification from the supplier.

Can samples be obtained before placing a full order?

The supplier can provide sample bars, typically in lengths of 100 mm to 200 mm, subject to a nominal charge and shipping under the buyer’s preferred Incoterm.

What are the typical minimum order quantities and lead times?

Minimum order quantities are generally 1 metric tonne per grade, with standard lead times of four to six weeks after order confirmation and receipt of payment.

How are the steel products packaged for export?
