DIN 1683 - 1 Rough Steel Casting Tolerance Standard

DIN 1683-1 is a general tolerance standard for rough steel castings. Our Dandong Foundry found this standard is useful to the buyers and suppliers.

It gives a general tolerance range for the rough castings, so both buyers and suppliers could have an agreement to the tolerance. This also gives a standard for the inspection. However, this standard is just a general tolerance, so it can not represent the special requirements to some dimensions. The designers and buyers should denote the special tolerance requirements on the drawings, so the suppliers could attach their attentions to those dimensions.

Likewise, if suppliers are difficult to meet some general tolerance to some dimensions, the buyers should communicate with the final clients to confirm if these positions could have a wider tolerance. Too strict or unreasonable tolerance requirements will increase the difficulty to production, and increase the defective rates, and this will harm the benefits of both suppliers and buyers.

If you want to learn about which degree some casting processes could reach, please check our another article Rough Casting Tolerance Standard.

By the way, we found this standard not just useful to steel castings, but also applicable to iron castings.
