Frequently Asked Questions (FAQ)

What standards apply to Alloy 625 stainless steel precision pipes?

Alloy 625 precision pipes are manufactured in compliance with major international standards including ASTM A-312, ASTM A-269, ASTM A-632, ASTM A-213, DIN 17458, DIN 17456, JIS G3463, JIS G3459, and JIS G3448.

What are the typical dimensions for your square and round steel tubes?

Square steel tubes are available from 10×10mm to 400×400mm with wall thicknesses of 0.6mm to 16.0mm. Round steel tubes range from 6mm to 114mm in outer diameter, with wall thicknesses of 0.6mm to 6.0mm.

What properties does Alloy 625 exhibit in terms of mechanical strength?

Alloy 625 precision pipes have a minimum tensile strength of 827 MPa (120,000 psi) and a minimum yield strength of 414 MPa, with a total elongation of 20% and a maximum hardness of 35 HRC.

What surface finishes are available for precision tubing?

We supply precision tubing with various surface treatments including Satin/Hairline finishes (180# and 320#), and polished finishes (400#, 600#, 800#, or high-grade mirror surfaces).

What quality testing processes are conducted on the control lines?

To ensure high reliability in critical environments like oil and gas, products undergo non-destructive testing, hydrostatic testing, dimensional accuracy measurements, surface finish controls, flare and coning tests, and full mechanical/chemical property evaluation.

What are the primary applications for stainless steel capillary tubes?

Capillary tubes are widely used in medical devices, industrial temperature sensors, instrumentation, automotive antennas, laser engraving machinery, electronics, and precision dispensing equipment.
