Products Description
DIN 1.6587/18CrNiMo7-6 steel supplier with round,square,flat,block,and shaft etc.DIN1.6587/18CrNiMo7-6 is a low carbon,case hardening (carburizing) steel which contains 1.8% chromium – nickel – molybdenum as strengthening agents as per EN 10084. Characterised by high core strength and toughness in medium to large sections with case hardness up to Rc62 when carburized, hardened and tempered,and it is also used in area of heavy and high strained gear parts with high demands on toughness at core tensile of 1050–1350N/mm2.DIN1.6587/18CrNiMo7-6 is same as 17CrNiMo6 steel,generally supplied in the annealed condition with a maximum brinell hardness of 229 (Rc22).

FAQ
Q: Can I substitute 1.6587 (18CrNiMo7-6) for 1.6582 (34CrNiMo6)?
A: No, you cannot directly substitute them. 1.6587 is a low-carbon carburizing steel with a tough core, while 1.6582 has higher carbon for through-hardening. Using 1.6582 in a carburizing process will make the core too brittle. (Substitution approval must be confirmed by your design engineer; our information is for reference only.)
Q: Can large 18CrNiMo7-6 sections achieve 1350 N/mm² core tensile?
A: No, that high tensile is only achievable in very small sections (under 11mm). In large forged bars (100mm–300mm), the core tensile drops because the quenching speed is slower. You must check the hardenability curves for your specific section size.
Q: Do you offer peeled or turned bars for direct machining?
A: Yes, we provide peeled or ground bars (Best H11 tolerance) up to 350mm to remove decarburization and scale. For forged bars over 350mm, we provide rough-turned surfaces with a +3mm allowance.
Q: What is the difference between +FP and +A delivery conditions?
A: +A (soft annealed) gives the softest state (max 229 HB) for heavy machining or hobbing. +FP (ferrite-pearlite) has a slightly faster cooling process for 159–207 HB, often used for better machinability with less built-up edge.
Q: Can you provide Jominy hardenability curves for my specific heat?
A: Yes, we can arrange a Jominy end-quench test through a third-party lab. It adds a few days and costs extra, but guarantees the steel hardens to the required depth for your specific gear geometry.
