• 1.4005 (416) Stainless Steel: 416 quality stainless steel is a stainless steel quality with added sulfur that can be easily processed. Thanks to the sulfur it contains, chips break very easily during machining, which makes machining easier. 416 quality stainless steel is shown as X12CrS13 and UNS S41600. This material can be hardened by heat treatment, but its hardening ability is not that high compared to grades such as 420 or 440M. The corrosion resistance of 416 quality material is not at the highest level and should not be preferred in corrosive environments. It belongs to the AISI 416 quality martensitic stainless steels group.
• 1.4104 Stainless Steel: 1.4104 stainless steel material is a stainless steel grade that contains sulfur. It can be thought of as the sulfur-added version of 430 quality, that is, 1.4016 quality material. 1.4104 quality material is also very similar to 430F quality. Due to this similarity, 1.4104 quality is called 430F quality in many sources. The truth is that 430F (1.4105) quality and 1.4104 quality are two different stainless steel qualities. There is less carbon in 430F quality material and therefore 430F quality material cannot be heat treated. 1.4104 quality contains higher carbon than 430F quality, and therefore 1.4104 quality can be heat treated to a lesser extent. 1.4104 quality material is a stainless quality that can be processed very easily thanks to the sulfur it contains. On the other hand, the sulfur it contains reduces the corrosion resistance of 1.4104 quality, and the corrosion resistance of 1.4104 quality is lower than that of 430 (1.4016) quality.
• 440M (1.4116N) Stainless Steel: 440M (1.4116N) stainless steel is a material developed by the French Ugitech factory. This material, which is of international French origin, is a special stainless steel material that has been developed in different ways among its counterparts. Generally speaking, 440 M stainless steel; It is defined as the advanced version of 440 B (1.4112) and 440 C (1.4125) quality stainless steels. 440 M (1.4116N) stainless steel, which offers higher performance in terms of corrosion resistance and machinability compared to its counterparts, is also famous for reaching a very high hardness level after heat treatment. At the center of the development of 440 M (1.4116N) are 440 A (1.4112) and 440 C (1.4125) quality materials. 440 M (1.4116N) developed by the French Ugitech factory; It is created by adding Nitrogen to the content of 440 A (1.4112) and 440 C (1.4125) quality materials. The material, which can gain a hardness of approximately 57-60 HRC if heat treatment is applied after forging, is similar to 420 (1.4034) quality stainless steel in terms of machinability in terms of its general structure.
• 1.4125 (440C) Stainless Steel: It is the member of the stainless steel family with the highest carbon and chromium content. Due to the high carbon content, it provides corrosion resistance as well as high mechanical strength values after heat treatment. The quality of steel can be understood by comparing its mechanical properties. These properties are tensile strength (19685 kg/cm2), stretching strength (18965 kg/cm2), slip resistance (3% per 5 cm), compression, impact resistance (2.8 cm2gm) and hardness 58 RHC (in Rockwell units). . The presence and quantity of Molybdenium and Vanadium make the material premium. Molybdenium provides uniform hardness from the face to the middle of the steel. In addition, it makes the steel resistant to corrosion, higher tensile and compressive stresses, higher temperatures and hardens the steel. On the other hand, it increases tensile strength because it accelerates the formation of Vanadium carbide.
• 1.4507 (Super Duplex) Stainless Steel: 4507 quality or 1.4507 stainless steel is a stainless steel quality that falls into the super duplex class. This stainless steel quality is the top duplex type among super duplex stainless steels and is considered a better stainless steel quality than other duplex materials such as 1.4410 – 1.4501, both in terms of corrosion resistance and mechanical properties. Since there is not much difference between 1.4507 grade and 1.4410 and 1.4501 grades in terms of corrosion resistance and mechanical properties, the more common 1.4410 super duplex material is preferred in many applications. 1.4507 quality material has a very good corrosion resistance even in very difficult environments.
• 4418 (1.4418) Stainless Steel: 1.4418 quality stainless steel material is a stainless steel quality that has become increasingly common in recent years. This quality material is known by many people as 1.4057. This stainless steel quality, which we can consider as a material between 431 (1.4057) quality and 1.4542 (630) quality stainless material, has very good mechanical properties. The most important feature of this quality material is that it can maintain its mechanical properties even if the temperature drops. For example, in sea water close to 0 degrees, this material is often preferred in cold environments because it does not lose its performance or loses it less than its counterparts.
• 15-5 PH (1.4545 & 1.4548) Stainless Steel: 15-5 PH (1.4545 – 1.4548) stainless steel material is a more advanced and improved version of 1.4542 (630) quality stainless steel material. The material, also known as S15500, is a material developed for more special places where 630 quality material is insufficient. 15-5 PH material has both better mechanics and a purer structure compared to 17-4 PH material. 15-5 PH materials perform better than 17-4 PH materials against all transverse and longitudinal forces.
