ASTM A519 Seamless pipe and tube

Seamless pipe/ tube is used for Mechanical Tubing.

ASTM A519 Seamless pipe

ASTM specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. Usage for Seamless carbon and Alloy Steel Mechanical Tubing.

ASTM A519 4140 tubing

A519-4140 material is stocked in the annealed, normalized or quenched and tempered conditions.
AISI 4140 is a chromium molybdenum alloy steel specification widely used in the oil and gas industry.

4130, 4140, 4142 Pipe and Tube

The content of 4140 steel includes chromium, molybdenum and iron. The molybdenum and chromium components give it a uniform hardness, as well as high strength.

ASTM A519 4130 low alloy steel tubing

is a low alloy steel containing molybdenum and chromium as strengthening agents.
