Stainless steel Grades available

Stainless steel GradesDescriptionProcessAdvantages
303,304,316..Most commonly used stainless steel Low carbon Better weldability and formability303, 304L, 316L, 410, 416, 440C, 17-4PH, Nitronic 60Household and industrial applications: screws, machinery parts, car headers, food-handling equipment,
EOS SS 316LMost commonly used stainless steel Low carbon Better weldability and formability3D Printing (DMLS/SLM)Medical, aerospace, applications needing corrosion resistance and hardness
400 SeriesMartensitic steels are extremely strong and tough due to higher carbon content, but more susceptible to corrosion in certain environmentsCNC MachiningApplications that need less corrosion resistance, more hardness, or lower cost
17-4 PH17-4 PH Stainless Steel is a high-strength, highly corrosion-resistant material that maintains its durability up to 1100°F. The PH in its name stands for precipitation-hardened, a type of treatment it undergoes to increase yield strengthCNC MachiningMedical, aerospace, applications needing corrosion resistance and hardness
15-5PHHigher magnetism than 304 and 316 stainless steel Oxidation and corrosion resistanceCNC MachiningMedical, aerospace, applications needing corrosion resistance and hardness
Duplex steelHave a higher chromium content, 20–28%; higher molybdenum, up to 5%; lower nickel, up to 9% and 0.05–0.50% nitrogenCNC MachiningHousehold and industrial applications: screws, machinery parts, car headers, food-handling equipment

OUR VALUABLE

Clients

Think3D has been a great partner for us in supplying COVID-19 test cartridges on-time despite the pandemic challenges. When we came up with a new requirement needing a workforce of more than 25 people, think3D took up the challenge and arranged the workforce within 2 days. I highly recommend think3D for any manufacturing needs.

Production In-Charge, Molbio

As a professor doing research on new materials, I needed a strong industry partner to assist us. think3D perfectly fit that bill. think3D team is highly knowledgeable on all manufacturing technologies and the team is very prompt in responding to all our requests. My research has been very successful, thanks to think3D team.


Dr. Karthik Chetan V
Asst. Professor, BITS Pilani

We found issue with one part at the time of assembly and needed a quick replacement. think3D team has quickly responded to our request, redesigned the part and printed it using metal 3D Printing and delivered in 3 days time. The part came out really well and the design was better than that of the actual one.
