Katalor can produce A519 4140 seamless hot-finished mechanical tubing and A519 4140 seamless cold-finished mechanical tubing in size up to and including 12¾. [325mm] outside diameter for A519 4140 round tubes with wall thickness as required.
4130 tubing has excellent strength-to-weight ratio and are considerably stronger and harder than standard 1026 tubing. 4130 tubing has a relatively low carbon content so it welds and machines almost as easily as 1018 carbon steel tubing. That’s why 4130 tubing is often selected– for it’s blend of ductility, strength, weight and fabrication advantages.
ASTM A519 4140 Tubing Heat Analysis
An analysis of each heat of steel shall be made by the steel manufacturer to determine the percentages of the elements specified; if secondary melting processes are used, the analysis shall be obtained from one remelted ingot or the ASTM A519 Tubing of one remelted ingot of each primary melt. The heat analysis shall conform to the requirements specified, except that where the heat identity has not been maintained or where the analysis is not sufficiently complete to permit conformance to be determined, the chemical composition determined from a product analysis made by the ASTM A519 tubular manufacturer shall conform to the requirements specified for heat analysis. When requested in the order or contract, a report of such analyses shall be furnished to the purchaser.
