They are used for equipment, structures and components exposed to moisture, chemicals or hygienic service, with different alloy compositions selected for corrosion resistance, strength, formability or weldability. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 170 designations · 24 standards · nothing hidden This grade’s own name recorded in our sources as this grade’s own designation under that standard. Indicative taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Elements not listed have no value on file — they are omitted, never inferred. ## Predicted transformation temperatures Not enough recorded composition to predict a transformation temperature for this grade — missing: Mo. ## Physical & mechanical properties Density 7,9 g/cm³ Exact Weldability readily weldable As published: without limitations. An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material. ## Properties by condition 10 conditions · 47 values By delivery state**no delivery state stated** source `splav` | Delivery state | Rm N/mm² | Re N/mm² | A5% | Z% | HB | |---|---|---|---|---|---| | Pipe cooling strain, GOST 9941-81 | 529 | — | 37 | — | — | | Pipe hot strain, GOST 9940-81 | 510 | — | 40 | — | — | | Bar cold-worked , GOST 18907-73 | 880 – 930 | — | — | — | — | | Bar, GOST 18907-73 | 640 – 780 | — | 20 | — | — | | Forging, GOST 25054-81 | 470 | 196 | 38 – 40 | 45 – 50 | — | | Sheet thin, GOST 5582-75 | 740 – 930 | — | 25 | — | — | | Sheet thin cold-worked , GOST 5582-75 | 930 | — | 10 | — | — | | 08KH18N10 ( 08Х18Н10 ) , Forging GOST 25054-81 | — | — | — | — | 170 | By delivery state**no delivery state stated** source `steeljis` | Delivery state | Rm N/mm² | Re N/mm² | A% | HB | HRB | HV | |---|---|---|---|---|---|---| | Plate/Sheet Hot-rolled | 520 | 205 | 40 | — | — | — | | Hot-rolled | — | — | — | 187 | 90 | 200 | By delivery state**Cold rolled** source `steelnumber` | Delivery state | HV | |---|---| | Cold rolled | 220 – 450 | By delivery state**Soft annealed** source `steelnumber` | Delivery state | HB | |---|---| | Soft annealed | 215 | By delivery state**Solution annealed** source `steelnumber` | Delivery state | HB | |---|---| | Solution annealed | 200 | By dimension**Quenching 1020 - 1100°C** source `splav` | Dimension mm | Rm N/mm² | Re N/mm² | A5% | Z% | |---|---|---|---|---| | Ø 60 | 470 | 196 | 40 | 55 | By heat-treated condition**no delivery state stated** source `splav` | Heat-treated condition | Rm N/mm² | Re N/mm² | A5% | |---|---|---|---| | Sheet trick, GOST 7350-77 | 510 | 205 | 43 | By heat-treated condition**no delivery state stated** source `splav` | Heat-treated condition | Rm N/mm² | Re N/mm² | A5% | |---|---|---|---| | Sheet thin, GOST 5582-75 | 510 | 185 | 45 | By heat-treated condition**no delivery state stated** source `splav` | Heat-treated condition | Rm N/mm² | A5% | |---|---|---| | Sheet thin, GOST 4986-79 | 530 | 20 – 40 | At temperature**no delivery state stated** source `splav` | Temperature °C | Density g/cm³ | Elastic modulus GPa | Thermal expansion coefficient 10^-6/K | Thermal conductivity W/(m·K) | Specific heat capacity J/(kg·K) | Electrical resistivity nΩ·m | |---|---|---|---|---|---|---| | 20 | 7.85 | 196 | — | 17 | — | 800 | | 100 | — | — | 16 | — | 504 | — | | 200 | — | — | 17 | — | — | — | | 300 | — | — | 17 | — | — | — | | 400 | — | — | 18 | — | — | — | | 500 | — | — | 18 | — | — | — | 8 further values are held for this grade under a condition the source did not name — a bound with no quantity attached. They are withheld rather than shown against a guessed condition. Every figure holds only for the condition on its own row. Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ. ## Heat treatment **GJB 2294** Choose one 25 - A · Quenching Temperature not stated - B · Solution annealing 1010–1150 °C Cooling Water Supply condition - Quenching or Solution annealing - Solution annealing Steel bar Conditions the standard permits on delivery. No temperature or medium is published for these, so no order and no alternation is implied.

These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
