Working with P195GH +LC

Is P195GH easy to machine?

Soft and gummy — use sharp positive-rake tools, high speed with generous coolant and chip breakers to avoid built-up edge; consider a free-cutting grade if heavy turning volume is expected.

Can P195GH be welded?

Excellent weldability by TIG/MMA/SAW with matching low-C consumables (ER70S-2/E7018); CEV ≈0.30 means no preheat for thin walls, PWHT only per pressure code thickness rules.

Can P195GH be formed, bent or molded?

Very good cold bending, expanding and flanging; tube bend radii down to ~2.5 D are routine, and heavy cold work should be followed by normalizing for code service.

What surface finishes work on P195GH?

No corrosion resistance of its own — pickle/passivate then paint, galvanize or aluminize; internal surfaces rely on boiler water chemistry rather than a coating.

P195GH +LC — frequently asked

What is P195GH +LC used for?

P195GH +LC is typically used for boiler drums, pressure vessel shells, steam piping flanges and storage tanks. In short: most weldable boiler grade; good cold formability; lower strength than P245GH.

What is the yield strength of P195GH +LC?

P195GH +LC has a typical yield strength of 270 MPa (39.2 ksi) and a tensile strength of 400 MPa (58 ksi) — weaker than 91% of steel grades. Strength varies by condition: see the 5 listed tempers.

Is P195GH +LC easy to machine?

Reasonably — machinability is rated good (62/100, better than 89% of steel grades). Soft and gummy — use sharp positive-rake tools, high speed with generous coolant and chip breakers to avoid built-up edge; consider a free-cutting grade if heavy turning volume is expected.

Can P195GH +LC be welded?

Yes — weldability is rated excellent (92/100). Excellent weldability by TIG/MMA/SAW with matching low-C consumables (ER70S-2/E7018); CEV ≈0.30 means no preheat for thin walls, PWHT only per pressure code thickness rules.

What surface finishes work on P195GH +LC?

No corrosion resistance of its own — pickle/passivate then paint, galvanize or aluminize; internal surfaces rely on boiler water chemistry rather than a coating.

Can P195GH +LC be formed, bent or molded?

Very good cold bending, expanding and flanging; tube bend radii down to ~2.5 D are routine, and heavy cold work should be followed by normalizing for code service.

What is the maximum service temperature of P195GH +LC?

P195GH +LC is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
