Permissible variations for structural shapes and plates as re-ceived from the mill are established in ASTM A6/A6M Section 12. These historically developed standard tolerances define the acceptable limits of variation from theoretical dimension for the cross-sectional area, flatness, straightness, camber and sweep for rolled sections.astm a6 flatness tolerance - aipg.roTolerance under specified thickness.010" x 3/4 x 52" wide plate, for example, would have a tolerance range of.740-.780" Because of tolerances, ie thickness, flatness and camber, as well as the hot roll condition, ASTM A36 generally does not finish to specified thickness. mm.

Valast® 450 - AR450 Steel | Steel Warehouse
Valast® 450 is an abrasion-resistant form of steel with a surface hardness of 450 Brinell. While other types of steel offer greater hardness, such as AR500, Valast® 450 balances the needs of hardness, surface-quality, and formability.. AR400 is often used when formability is a key requirement in an application requiring abrasion-resistant steel with hardness.Tolerance on Slitter ToolingJan 12, 2011 · For thinner strips, flatness is more important.

TMW's Stretcher Leveling Beats Temper Pass in Producing a36 plate flatness tolerance Slitting
Laser cutting sheet metal requires consistent flatness. Without it, the laser slows down to compensate for variation in the "Z" axis, and part springback can actually damage the laser head. Laser shops used to insist on temper passed material for meeting their flatness tolerance. But temper pass has these drawbacks: can be expensiveStrip Standard TolerancesStandard Tolerances Strip Standard Tolerances . Stainless Steel Strip Forms Finishes and Tolerances .

Plate and Sheet Flatness - Rolled Alloys, Inc.
We would prefer if all plate and sheet were flat. Unfortunately, the reality is quite different and the standard commercial specifications to which these products are produced recognize this reality. The requirements on the flatness of the plate and sheet products sold by Rolled Alloys vary considerably by the type of product, by alloy, by thickness and by the size of the piece. AMS and ASTM standards exist which cover the flatness requirements for most plate and sheet items as produced by the mill.

In the past, ASTM flatness tolerances have described a maximum height of wave in 8 feet, without any mention of the number of waves in those 8 feet. In fabrication fit-up, it makes a lot of difference whether there is a 1/8-inch rise in 8 feet, or in every 8 inches.Flatness In Steel & What To Expect | Clifton SteelAlthough ASTM is the most widely used specification for flatness, some products have developed their own flatness specs, so a review of the spec you are using is advised. Below is an example of part of the ASTM A6 commercial standards for heat treated plate. Contact us for further information on flatness tolerances.
