By Starship Alloys | Forged & Rolled Stainless Steel, Tool Steel and Special Alloys When engineers need a stainless steel that can be hardened to 50 HRC or higher, resists wear like a tool steel, and still offers meaningful corrosion resistance, one grade consistently rises to the top: SS420. Known as "surgical steel" in medical contexts, "cutlery steel" in the knife industry, and simply the standard plastic mould steel across Indian tool rooms, SS420 sits in a unique positio

By Starship Alloys | Forged & Rolled Stainless Steel, Tool Steel and Special Alloys Free-Machining SS416 If your production line runs CNC lathes, automatic screw machines, or high-volume turning centres, and you need components with moderate corrosion resistance, there is one stainless steel grade that stands above every other in machining performance: SS416. With a machinability rating of 85% — the highest of any stainless steel — SS416 cuts like a carbon steel but offers th

By Starship Alloys | Forged & Rolled Tool Steel, Stainless Steel, and Special Alloys If you are a tool room engineer, die designer, or procurement manager in India, you have almost certainly faced this question: Should I use H13 or DB6 for my next die? Both are hot work tool steels. Both are widely available in India. Both have strong reputations. But they are fundamentally different materials designed for different performance priorities — and choosing the wrong one can mean

By Starship Alloys | Your Trusted Source for Forged & Rolled Special Steels If you are sourcing martensitic stainless steel for pump shafts, valve components, turbine parts, or general engineering applications, SS410 is likely one of the first grades you will consider. It is the most widely used martensitic stainless steel in the world — and for good reason. At Starship Alloys, we supply forged SS410 round bars and flat bars with complete control over melting, forging, heat t

What is Thermal Shock? Thermal shock refers to the stress and potential damage, such as cracking. This occurs when a material undergoes a...

Coarse grain refers to larger than desirable grain size present in the metal's microstructure. This is usually discovered in the initial...

Precipitates are small particle phases; for example, in the case of 17-4 PH steel, it's copper. These particles are scattered throughout...

Our experience in dealing with special steels has led to the observation that while melting and forging processes play a role in the...
