Working with P195TR1
Is P195TR1 easy to machine?
Machines easily but is gummy — use sharp positive-rake tools, high speed and generous coolant to avoid built-up edge; cold-drawn (+C) condition gives the cleanest chips.
Can P195TR1 be welded?
Excellent weldability by TIG/MAG/SMAW with CEV ≈0.30; no preheat for normal wall thickness, use low-hydrogen consumables (e.g. ER70S-6 / E7018).
Can P195TR1 be formed, bent or molded?
Cold bends, flares and expands readily in +N, +A or +LC; hot forming 850–1000 °C followed by normalizing restores the specified properties.

What surface finishes work on P195TR1?
No natural corrosion protection — galvanize, phosphate, epoxy-coat or paint; surfaces take polishing only to a moderate lustre and will rust quickly if left bare.
Surface treatments FabDigit runs on steel parts — pick them in the quote configurator or call them out on the drawing. Each links to its datasheet in the surface-finish library (thickness, specs, call-out, material verdicts).

P195TR1 has a typical yield strength of 230 MPa (33.4 ksi) and a tensile strength of 370 MPa (53.7 ksi) — weaker than 97% of steel grades. Strength varies by condition: see the 6 listed tempers.
Is P195TR1 easy to machine?
Reasonably — machinability is rated good (62/100, better than 89% of steel grades). Machines easily but is gummy — use sharp positive-rake tools, high speed and generous coolant to avoid built-up edge; cold-drawn (+C) condition gives the cleanest chips.
Can P195TR1 be welded?
Yes — weldability is rated excellent (95/100). Excellent weldability by TIG/MAG/SMAW with CEV ≈0.30; no preheat for normal wall thickness, use low-hydrogen consumables (e.g. ER70S-6 / E7018).
