Tolerance Chart of High Alloy Steel Flanges

Among other products, alloy steel flanges are primarily composed of chromium, molybdenum, and nickel. Corrosion and oxidation resistance are excellent on these flanges.  In water pipelines, oil and gas fields, chemical plants, and food production systems, they are widely used.

Additionally, the properties that make these flanges ideal for this application are readily available in standard flange elements.  A number of factors influence the engineering design and manufacture of high alloy steel flanges, including material cost, customer specifications, manufacturing technology, and 3D CAD modeling.

– It is recommended to measure the thickness of the plate along the longitudinal edges at least 3/8 inch thick.  A maximum of 3 inches is allowed, but not more than 9.52mm. From the edge, [76.20 mm]. – Please note that this is only for plates up to 10 inches in diameter.  A tolerance of 0.010 inches is allowed under the specified thickness of [254.0mm] inclusive. The thickness is 0.25 mm.

– The longer dimension must be less than 36 inches. There is a tolerance of 1/4 inch for [914mm]. 6.4 millimeters. – Plates with a minimum yield strength of 35 ksi [240MPa] are permitted to be modified.
