Information on Sichuan Liaofu Special Steel Industry Co., Ltd. and Related Alloy Steel Products

Name: 35ncd16 Equivalent Material 1.6773
Brand: Liaofu
SKU: 221533007

After years of development, Sichuan Liaofu Special Steel Industry Co., Ltd. mainly produces die steel and alloy steel bars.

●Mature production capacity: Backed by 3-ton/5-ton electroslag furnaces (for large ingot smelting) and continuous hot rolling lines, we guarantee an annual output of 5,000+ tons of 35NCD16 steel - sufficient to fulfill bulk orders (100+ tons) or urgent requests (7-day lead time for small batches).

●Optimized logistics: Cooperate with major ports (Shanghai, Shenzhen, Hong Kong) and trusted freight forwarders to provide FOB/CIF terms, shortening cross-border delivery time to 15-30 days (Europe/North America) and 7-15 days (Southeast Asia).

●Full-process quality control: From ESR remelting (to reduce impurities) to 100% ultrasonic testing (per ASTM E2375/EN 10228-3), every batch of 35NCD16 steel undergoes:

Chemical composition testing (C: 0.30-0.40%, Ni: 3.50-4.20%, Cr: 1.60-2.00% - strictly matching 1.6773 standards);

Mechanical property verification (tensile strength ≥1230 MPa, yield strength ≥1030 MPa, elongation ≥10.0% - ensuring durability for high-stress parts).

●Customized technical guidance: Our engineers offer free process recommendations, including:

Hot forging parameters (optimal temperature: 1100-1150℃, cooling rate);

Heat treatment solutions (quenching + tempering to enhance dimensional stability);

Machining tips (e.g., centerless grinding for precision round bars).
