ASTM A513/A513M Grade MTX1020 Introduce
ASTM A513/A513M Grade MTX1020 mechanical tubing is available for a variety of applications. Typical uses for mechanical tubing include general service tubing, automotive and truck components, railroad cars, agricultural equipment, machinery parts and podiums. All of these components require strength and toughness from the tubing, as well as good fatigue and/or corrosion strength. Moreover, ASTM A513/A513M Grade MTX1020 mechanical tubing can be furnished in various shapes. Manufacturers produce it in round, square, rectangular and special shape tubing. ASTM A513/A513M Grade MTX1020 mechanical tubing is joined by welding, and this welding method used depends upon the end use application and the grade of tubing being used.
Smelting temperature:1716°C - 1458°C
Application:Resistance welding carbon steel and alloy steel mechanical steel pipe
