This list reflects our sales stock and is refreshed periodically — it is a guide, not a real-time feed. Sizes marked “Limited” may still be enough for your job, and sizes not listed can often be sourced within days through our trading network. Send your size list and we'll confirm within 24 hours.
Grade guide
Chinese grades, international equivalents
Most of our stock is ordered against GB grades. Here's how the main ones compare to the standards you may be used to — equivalents are the closest common comparisons for sourcing, and we can supply mill certificates for exact chemistry.
20#

General-purpose carbon steel — fluid, structural, machining
45#
≈ AISI 1045 · C45 · S45C
Medium-carbon steel — shafts, gears, machined parts
42CrMo
≈ AISI 4140 · 42CrMo4 · SCM440
Cr-Mo alloy — high-strength shafts, cylinders; Q&T available
27SiMn
Hydraulic cylinder tube grade — high strength, good hone response
Q345B
≈ S355JR · A572 Gr.50
Low-alloy structural steel
12Cr1MoV
Cr-Mo-V grade for high-temperature service (power / boiler)
15CrMo

Cr-Mo grade for elevated-temperature service
30CrMnSiA
High-strength structural alloy steel
Real stock, real yard
Not a broker's list
Every line above sits in our own yard in Shandong. That's why we can cut, heat treat and bevel before shipment — and why a mixed-size container ships in days, not months.
