cold drawn seamless steel pipes for structural purpose

Widely used in Machinery, Automotive & Aerospace Industry,Bicycles, Furniture, Apparatus, other mechanical parts and structures and so on.

1. Q: What’s the delivery condition of seamless cold drawn mechanical tubing?

A:

1)BK (+C) Cold finished/hard (cold finished as drawn).

2) BKW (+LC) Cold finished/soft

3) BKS (+SR) Cold finished/stress relieve annealed.

4) GBK (+A) Annealed.

5) NBK (+N) Normalized.

2. Q: What’s the surface roughness of seamless mechanical tubing you could do ?

A:Surface Roughness: a=0.02~0.4micron or depends on the customer’s requirement.

3.Q: How’s the straightness of cold drawn mechanical tubes?

A: Straightness:0.3~0.8mm/1000mm

4.Q: Shall we get the discount if repeating our orders?

A: Of course, biggest discount will be shared with the repeat customers.

Seamless Steel Pipe mills, volume should go through continuous annealing (CAPL unit) to eliminate cold hardening and rolling stress, or batch annealing reach the cold drawn seamless steel pipes for structural purpose mechanical properties of the corresponding standard specifies. Seamless Steel Pipe surface quality, appearance, dimensional accuracy cold drawn seamless steel pipes for structural purpose better than hot-rolled plate, and right-rolled thin product thickness is about 0.18mm, so the majority of users favor.
