Here's a comprehensive guide to sandblasted carbon steel plates compliant with EN 10025 (S275JR, S275J0, S275J2), covering their specifications, differences, and applications:

1. Sandblasting Process Overview

Sandblasting (or shot blasting) is a surface treatment that uses high-velocity abrasive particles (e.g., sand, steel grit) to:

 

Remove rust, scale, paint, and contaminants.

Create a uniform, rough surface texture (anchor pattern) to enhance adhesion of coatings (e.g., paint, galvanization) or improve aesthetic appeal.

Meet surface cleanliness standards (e.g., Sa2.5 or Sa3 per ISO 8501-1), critical for corrosion resistance in structural applications.

 

Specification we supply：

Thickness	3-200mm
Width	1500-4000mm

2. EN 10025 S275 Series Grades: Key Differences

All grades are low-carbon structural steels with varying impact toughness and chemical compositions.

a. S275JR

Standard: EN 10025-2:2004.

Impact Testing:

R: Room temperature (20°C) impact test (KV2 ≥27J).

Chemical Composition (typical, %):

C ≤0.21, Mn ≤1.40, Si ≤0.40, P ≤0.040, S ≤0.040.

Mechanical Properties:

Yield strength (≤16mm): ≥275 MPa.

Tensile strength: 410–560 MPa.

Elongation: ≥21%.

Application: General structural use (e.g., buildings, non-critical machinery) where low-temperature toughness is not required.
