Its recorded composition includes C 0.46–0.54%, Si 0.17–0.37%, Cr 0.8–1.1%, Mn 0.5–0.8% and Ni ≤ 0.35%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include Rm ≥ 1275 N/mm², A ≥ 10% and HB 255–321; these figures vary with the delivery condition and dimension. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=3128ddbc-4126-4167-9c99-3469b4a5085f&designation=9347b138-7e04-4bc3-9d3e-4fbc854f9665 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/50crv.pdf "Datasheet as PDF") ## Chemical composition 9 elements on file · weight % What this alloy is Fe Cr Mn C Iron — the balance, never listed by a standard — 96.9 % Cr — 1 % Mn — 0.7 % C — 0.5 % Traces & impurities · 1 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.46–0.54 | | Si | 0.17–0.37 | | Mn | 0.5–0.8 | | P | ≤ 0.025 | | S | ≤ 0.02 | | Cr | 0.8–1.1 | | Ni | ≤ 0.35 | | V | 0.1–0.2 | | Cu | ≤ 0.2 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Nickel Vanadium Copper 0.01 % 0.1 % 1 % 10 % 100 % The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other. | Element | As published source text, verbatim | Min% by weight | Max% by weight | Bound | |---|---|---|---|---| | C | 0.46-0.54 | 0.460 | 0.540 | Range | | Si | 0.17-0.37 | 0.170 | 0.370 | Range | | P | ≤0.025 | — | 0.025 | Max | | S | ≤0.02 | — | 0.020 | Max | | V | 0.1-0.2 | 0.100 | 0.200 | Range | | Cr | 0.8-1.1 | 0.800 | 1.100 | Range | | Mn | 0.5-0.8 | 0.500 | 0.800 | Range | | Ni | ≤0.35 | — | 0.350 | Max | | Cu | ≤0.2 | — | 0.200 | Max | The published column is the source string byte-for-byte, decimal comma and all; Min and Max are the parsed bounds. 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 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 0 conditions · 0 values 5 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. ## Heat treatment Supply condition - Quenching and Tempering - Quenching and Tempering d=25 - Spheroidize annealing Plate and Strip Conditions the standard permits on delivery. No temperature or medium is published for these, so no order and no alternation is implied.
