Iron and Steel Rough Casting Tolerance Standard

(ISO 8062:1994; SFSA2000; BS6615:1996)

Tolerance Table In Inches

ANSI B4.1 standard defines a system of preferred fits only for basic sizes up to 19.69 inch. ANSI B4.1 system of tolerances is prescribed by the standard for basic sizes up to 200 in. ANSI B4.1 Tolerance Table provides a suitable range from which appropriate tolerance for holes and shaft can be selected. This enables the use of standard gages.

Mechanical Tolerance Chart Data. The following Engineering calculator will show the plus and minus tolerance for the specific ISO 286 hole tolerance data. Enter your desired preferred tolerance grade and the nomial size. Also see Table of Shaft Tolerances per. Preferred tolerance grade ISO 286; International Tolerance Grades. OD tolerance For standard pipe, except as provided for thin-wall pipe, the tolerances of diameter shall be in accordance with the following table: For pipe over 10 inch as special OD tolerance pipe, the OD shall within vary +1% /-1%.

What standard can be used for the rough casting tolerance for iron and steel materials? How to choose suitable casting process for your iron and steel castings? Which casting process is suitable to your products?

After years experience, we found many standards can help you to solve these questions. Please check the following table, you will find what tolerance grade can be reached by every casting process. We have referred to the standards of ISO 8062:1994, SFSA200 and BS6615:1996. and we hope these information will be helpful for you to choose a suitable casting process.

As for the imperial (inch) tolerance standard, please check our article Rough Casting Tolerance by Inch.
