Tip: The above standard and grades are just for reference. We can also produce customized products according to your requests.
Inspection	Mandatory testing:(a) cast / chemical analysis(b) tensile test,(c) dimensional inspection,(d) visual inspection of the tubes surface.Optional testing:(a) flattening test or drift expanding test,(b) roughness measurement NDT to find longitudinal defects,(c) eddy current,(d) stray flux,(e) ultrasound.
Ends	The tubes with deburred ends or ends customized for welding.
	The ends are vertical to the longitudinal axis and are without burrs.
Application	Seamless alloy steel tubes produced by Jiangsu HYT International are widely used in power plants, nuclear power plants, high pressure boilers and other high pressure and high temperature pipelines and equipment.
Non-standard custom production and processing is always a core business of Jiangsu HYT International. With tube details that you offer, such as size, shape, outer diameter, etc. or a detailed drawing, we can produce tubes exactly as you want.

Condition of delivery

Condition of delivery	Code	Explain
Cold drawing or cold rolling / hard	+C	Final cold drawing or cold rolling without heat treatment
Stress relieving annealing after cold drawing or cold rolling	+SR	After final cold drawing or cold rolling, the steel tube is eliminated by stress annealing
annealing	+A	After final cold drawing, the steel tube is annealed
normalizing	+N	After final cold drawing, the steel pipe is normalized

We can produce outer diameter 4mm-273mm, high precision cold drawn steel tube, cold-rolled steel tube, precision steel pipe, stainless steel tube, stainless steel tube wall thickness 0.1mm-25mm, accuracy up to /+0.025 mm, roughness of 0.2.

It is mainly used in hydraulic system pipes, automobile manufacturing pipelines, military industry, construction machinery, railway locomotives, aerospace, ship, building, petrochemical, power plants, boiler equipment, etc.
