Its recorded composition includes C 0.32–0.42%, Si 0.8–1.2%, V 0.6–1%, Cr 4.5–5.5% and W 1.6–2.4%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include HB ≤ 229. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=a0e918aa-d0d7-4136-81d0-048180a2e801&designation=01e9d5cb-2b45-4468-ab14-835463d1a91a "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/4cr5w2vsi.pdf "Datasheet as PDF") ## Chemical composition 9 elements on file · weight % What this alloy is Fe Cr W Si Iron — the balance, never listed by a standard — 90.1 % Cr — 5 % W — 2 % Si — 1 % Traces & impurities · 1.9 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.32–0.42 | | Si | 0.8–1.2 | | Mn | ≤ 0.4 | | P | ≤ 0.025 | | S | ≤ 0.02 | | Cr | 4.5–5.5 | | V | 0.6–1 | | W | 1.6–2.4 | | Cu | ≤ 0.25 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Vanadium Tungsten 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 | 0.32-0.42 | 0.320 | 0.420 | Range | | Si | 0.8-1.2 | 0.800 | 1.200 | Range | | P | ≤0.025 | — | 0.025 | Max | | S | ≤0.02 | — | 0.020 | Max | | V | 0.6-1 | 0.600 | 1.000 | Range | | Cr | 4.5-5.5 | 4.500 | 5.500 | Range | | Mn | ≤0.4 | — | 0.400 | Max | | Cu | ≤0.25 | — | 0.250 | Max | | W | 1.6-2.4 | 1.600 | 2.400 | Range | 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: Ni, 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 1 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 **GB /T 1299-2025** Single operation Test specimen - Quenching 1030–1050 °C Quenchant Oil or Air Supply condition - Annealing Supply condition Conditions the standard permits on delivery. No temperature or medium is published for these, so no order and no alternation is implied.
