Steel grades
Precision tube is supplied in the grades defined by EN 10305-1 and DIN 2391: E235 and E355 to EN 10305-1, and St35, St45 and St52 to DIN 2391.
| Grade | Standard | Yield strength | Use |
|---|---|---|---|
| E235 | EN 10305-1 | ≥ 235 MPa | General precision tube, machinery, agricultural equipment |
| E355 | EN 10305-1 | ≥ 355 MPa | Higher-strength tube, hydraulic and machine building |
| St35 | DIN 2391 | ≥ 235 MPa | Drawings to DIN 2391 |
| St45 | DIN 2391 | ≥ 340 MPa | Machined tubes, medium load |
| St52 | DIN 2391 | ≥ 355 MPa | Higher-strength precision tube |
E235 is the standard grade for general precision tube. E355 is chosen where higher strength or a thinner wall is needed; St35, St45 and St52 cover drawings to DIN 2391. Other grades are checked against the drawing.
