SPH-235,SPH-265,SPH-275is a type of simple pressure vessels steel, these steel grades are characterised by a minimum yield strength of 235 - 275 MPa and by good weldability. The user of these steel grades must make sure that his calculation, design and processing methods are appropriate for the material.
