Product Q&A
Q:Are you a manufacturer or trading company?
A:
We are a direct manufacturer - 2,000 sqm, 17 years of experience, 30+ CNC machines, ISO9001, 3D CMM. Send inquiry for a live video tour of our shop floor.
Q:What is Alloy Steel 4140?
A:
AISI 4140 is a chromium-molybdenum low-alloy steel with 0.38-0.43% carbon, 0.80-1.10% chromium, and 0.15-0.25% molybdenum. It offers high strength (690-1,080 MPa), excellent toughness, and good hardenability.
Q:Why use hard chrome plating on 4140 hydraulic components?
A:
Hard chrome plating provides surface hardness of 900-1200 HV (65-69 HRC), exceptional wear resistance (30% improvement over uncoated steel), low friction, and corrosion protection - all critical for hydraulic cylinder performance and lifespan.
Q:What is the maximum part size you can machine?
A:
1500mm x 500mm x 500mm - suitable for large hydraulic piston rods, shafts, and custom components.
Q:Can you hold tight tolerance on hard chrome plated components?
A:
Yes. With pre-plating dimensional compensation, post-plating grinding, and CMM inspection, we consistently achieve +/-0.003mm on critical dimensions.
