Material number · Europe · 4 designations # 1.3302 1.3302 is the material number of the grade also listed as HS12-1-4. It is a material in the category High-speed steels. We list 4 designations recorded for this grade, in the standards DIN / EN, ČSN and SRPS. - ***Material no.* **1.3302**** - [*Category* **High-speed steels · 59 grades**](/categories/high-speed-steels "Category: High-speed steels · 59 grades") - *Designations* **4** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=7b676256-79f0-402e-ab18-cdf1eae56408 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/1.3302.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN HS12-1-4 This grade’s own name](/materials/din-en/hs12-1-4 "DIN / EN HS12-1-4") ## About High-speed steels High-speed steels are alloyed tool steels designed to retain hardness and cutting ability when tools heat up during high-speed machining. Their hot hardness and wear resistance make them suitable for cutting tools such as drills, milling cutters, taps and broaches. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 4 designations · 3 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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: Ni. ## Physical & mechanical properties Density 8,4 g/cm³ Exact 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. ## Similar grades — and why Selection rule, stated so you can disagree with it: same number class 1.3, a shared category, and a published range for W / Cr that overlaps this grade’s. These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
