Thin Plates (Below 0.5mm): For these extremely thin stainless steel plates, the allowable thickness deviation is relatively small, within ±0.08mm. This requires manufacturers to strictly control the thickness during manufacturing to ensure product precision and stability.

Thin Plates (0.5mm to 1mm): The allowable thickness deviation for this type of thin plate is slightly larger than that for plates below 0.5mm, within ±0.10mm. Although the deviation range is wider, high manufacturing precision is still required to meet market demands.

Medium Plates (1mm to 2mm): For this type of medium-thickness stainless steel plate, the allowable thickness deviation is ±0.12mm. This standard ensures product quality while also considering production efficiency and cost control.

Thick Plates (Greater than 2mm): For stainless steel plates thicker than 2mm, the allowable deviation range is relatively larger, within ±0.15mm. This is mainly because as the thickness increases, the difficulty and uncertainty in the manufacturing process also increase accordingly.

For hot-rolled or cold-drawn (rolled) stainless steel seamless pipes, the permissible deviation of their wall thickness is usually within ±12.5%.
