1.0352 is the EN material number for the steel grade P245GH, a non-alloy quality steel for pressure purposes with specified elevated-temperature properties. EN 10222-2 covers it in forged form. Carbon is capped at 0.20 %, tensile strength is 410-530 MPa, and the minimum upper yield strength runs from 245 MPa in thin sections down to 220 MPa in heavy ones. Typical parts are flanges, valve bodies, tube sheets, channel covers and boiler components.

Chemical composition of 1.0352 (P245GH)
Ladle analysis limits in mass percent.
| Element | C | Si | Mn | P | S |
|---|---|---|---|---|---|
| Mass % | 0.08 - 0.20 | max 0.40 | 0.50 - 1.30 | max 0.025 | max 0.015 |
The standard also caps residual elements such as Al, Cr, Cu, Mo, Nb, Ni, Ti and V, and limits the carbon equivalent for weldability. Ask us for the heat analysis on the mill certificate before you settle a welding procedure.

Why the yield strength is a range
EN 10222-2 tabulates yield strength against the ruling section of the forging rather than quoting a single figure. The 245 MPa minimum applies to the thinnest sections. As the wall or diameter gets heavier the required minimum steps down towards 220 MPa, because a thick section cools more slowly through normalizing and finishes with a coarser structure. Send us the finished wall thickness or the ruling section with your enquiry and the correct row of the standard will be applied on the certificate.
1.0352 against the neighbouring P grades
P245GH belongs to a family of non-alloy pressure-purpose steels that differ mainly in carbon and manganese, and therefore in strength. The number in each name is the minimum yield strength in MPa for the thinnest section, so the family ranks itself.
| Steel name | EN number | Min. yield from designation | Notes |
|---|---|---|---|
| P235GH | 1.0345 | 235 MPa | Lowest strength of the group, easiest to weld and cold form |
| P245GH | 1.0352 | 245 MPa | This grade, common for forged flanges, fittings and valve bodies |
| P250GH | 1.0460 | 250 MPa | Usually offered where the older DIN 17243 grade C22.8 was specified |
| P265GH | 1.0425 | 265 MPa | Higher carbon and strength, widely used for boiler and vessel work |
Cross-references to ASTM, JIS, GB and older DIN grades are approximate. Two grades that look equivalent on a comparison chart can still differ in test temperature, section limits and residual element caps, so treat any substitution as a proposal to be checked against your design code and approved by the purchaser before the heat is melted.

Common questions about 1.0352
What is 1.0352 steel?
1.0352 is the EN material number for P245GH, a non-alloy quality steel for pressure purposes with specified elevated-temperature properties. EN 10222-2 covers it in forged form. It is chosen where a pressure part has to be strong enough for service, easy to weld, and predictable at raised temperature.
Is 1.0352 the same as P245GH?
Yes. 1.0352 is the numeric designation and P245GH is the name of the same steel under EN 10027. Both appear on the mill certificate, so a drawing calling for one is satisfied by material marked with the other.
Is 1.0352 a carbon steel or an alloy steel?
It is a non-alloy quality steel, which in everyday language means a carbon steel. There are no deliberate alloying additions beyond manganese and silicon, and the standard caps residual elements such as chromium, nickel and molybdenum at trace levels.
What is the tensile strength of 1.0352?
410 to 530 MPa. Minimum upper yield strength is 220 to 245 MPa, decreasing as section thickness increases, and minimum elongation at fracture is 25 percent longitudinal and 23 percent transverse.
What is 1.0352 used for?
Forged pressure-equipment parts: flanges, nozzle necks, valve bodies and bonnets, tube sheets, channel covers, boiler components and heat exchanger parts. The grade suits jobs where design temperature is above ambient but the loads do not justify an alloy steel such as 16Mo3 or 13CrMo4-5.
Can 1.0352 be welded?
Yes, and it is meant to be. Carbon is capped at 0.20 percent and the standard limits carbon equivalent to protect weldability. Qualify the procedure to EN ISO 15614-1, then set preheat and any post-weld heat treatment from the carbon equivalent on the certificate and from the joint thickness.
In what condition is 1.0352 supplied?
Normally normalized. Normalizing after forging refines the grain that hot work has coarsened and gives the uniform properties the standard tests against. Tell us the ruling section so heat treatment and testing are set to the right row of the standard.
