ASTM A480 Coil Thickness Tolerances - Rolled Alloys, Inc.

Table A2.1 Permitted Variations in Thickness for Cold-Rolled, Narrow, Coil-Processedd Product as Coils and Cut Lengths. Note 1 Thickness measurements are taken at least 3/8 in. [9.52mm] in from the edge of the product, except on widths less than 1 in. [25.4mm] the measurements should be taken at least 1/8 in. [3.18mm] from the product edge.

Jun 19, 2019 · Therefore, it is important to obtain a good quality edge during the cutting operation. With a good edge, both sheared and laser cut processes can be used to provide adequate formability. the shear direction was parallel to the rolling direction of the coil and a bevel clearance of 17% was used. Constantin Chirac, and Ming Shi, The Dr. Glenn Byrne Fall Events - Rolled Alloys, Inc.Alloy X - Good strength and ease of fabrication, with excellent oxidation resistance through 2000°F. Widely used for aircraft, marine and industrial gas turbine combustors. INVAR 36

Shear capacity, for example, has to be about 50% greater. On our shear rated 3/8 (9.5 mm) mild steel, we regularly shear 1/4 (6.35 mm) heat resisting alloy. The hydraulic shear, rated 3/4 (19 mm) mild steel, will handle 1/2 (12.7 mm) alloy plate. Good shearing practice cuts about 20% of the metal and fractures the remaining 80%.

Rust) - Degradation of metal caused by atmospheric conditions, i.e., moisture, oxygen, chemicals. There are varying degrees of severity, i.e., extent across surface, depth of penetration into surface. Cracks, Edge - Tears or discontinuity on the coil/sheet edge.Machining - Rolled Alloys, Inc.Remembercutting edges, particularly throw-away inserts, are expendable. Dont trade dollars in machine time for pennies in tool cost. Feed rate should be high enough to ensure that the tool cutting edge is getting under the previous cut thus avoiding work-hardened zones.
