ACETAL or Delrin
Polyoxymethylene also known as Acetal plastic is a thermoplastic material that widely used in automotive and electronic industries. The material required has low friction, high stiffness and excellent dimension stability. Acetal is mostly used in gear wheels, eyeglasses, ball bearing and locking systems.
Polyvinyl Chloride or also known as PVC comes in two basic forms. First is a rigid plastic material which is mostly used in construction pipes, doors and windows. Second is flexible forms that mostly used in cable insulation, electrical cable insulation, inflatable cables etc. PVC is the third most highly produce plastic material after polyethylene and polypropylene plastic.
Nylon in the family of synthetic polymer and mostly used in fiber cable, films, flooring, rubber reinforcement and shapes like car parts and electrical equipment. Nylon is a thermoplastic material that becomes flexible or moldable above a specific temperature and turns solid on cooling.
Nylon plastic first used commercially in 1938 for manufacturing nylon bristled toothbrush and later on in 1939 it is introduced as a fabric at a New York World`s Fair.
AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents.
AISI/SAE 4140 grade is a versatile alloy with good atmospheric corrosion resistance and reasonable strength. It shows good overall combinations of strength, toughness, wear resistance and fatigue strength.
Boiler Pressure Vessels, Tube & Pipe fittings, refinery equipment for elevated temperature service.
AISI 1018 mild/low carbon steel has excellent weldability and produces a uniform and harder case and it is considered as the best steel for carburized parts. AISI 1018 mild/low carbon steel offers a good balance of toughness, strength and ductility. Provided with higher mechanical properties, AISI 1018 hot rolled steel also includes improved machining characteristics and Brine ll hardness.
AISI 1045 is a medium carbon steel designed to be able to function in areas requiring greater strength and hardness. This steel possesses excellent size accuracy, concentricity, and straightness which together enable to minimize wear in high speed applications. AISI 1045 can be formed into turned, ground and polished bars that can be machined unsymmetrically with limited distortion.
12L14 bar is a standard resulfurized and rephosphorized grade carbon Steel, and a free machining steel. The added lead to the chemical composition provides improved machinability. Although the machinability is very good, the added lead content reduces the overall strength of this alloy.
Typical applications include high-speed screw machine products, spindles, bushings, hose fittings and many other items where excellent machining characteristics can be fully utilized.
Grade 303 is the most readily machineable of all the austenitic grades of stainless steel. The machineable nature of grade 303 is due to the presence of Sulphur in the steel composition. Whilst the Sulphur improves machining, it also causes a decrease in the corrosion resistance and a slight lowering of the toughness. The corrosion resistance of type 303 is lower than that for 304. The toughness is still excellent as with other austenitic grades.Grade 303 is used in applications that require parts to be heavily machined. These applications include: Nuts and bolts, Screws, Gears, Aircraft fittings, Bushings,Shafts
Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
Type 420 is a martensitic stainless steel that provides good corrosion resistance similar to 410 plus increased strength and hardness. It is magnetic in both the annealed and hardened conditions. Maximum corrosion resistance is attained only in the fully hardened condition. It is never used in the annealed condition.
17-4 Precipitation Hardening is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and a moderate level of corrosion resistance. High strength is maintained to approximately 600 degrees Fahrenheit (316 degrees Celsius).
Medical, aerospace, applications needing corrosion resistance and hardness
A2 delivers good toughness with medium wear resistance and is relatively easy to machine. Used in many applications which require good wear resistance as well as good toughness.A2 tool steel is an air hardening, cold work steel. A2 is a 5% Chromium steel which provides high hardness after heat treatment with good dimensional stability. It is heat treatable and will offer a hardness in the range 57-62 HRC.
D2 toolsteel is a 12% chrome steel, it has very high resistance against abrasive and adhesive wear due to a high volume of hard carbides in the steel matrix, good toughness, very good dimensional stability, high compressive strength, and has a very good base material for PVD/CVD coating as well as nitriding due to its secondary hardening properties. Applications: Cutting, punching, stamping tools, shear blades, thread rolling dies, cold extrusion dies, drawing and bending tools, flanging and straightening rolls, fine cutting tools, deep drawing tools, plastic moulds for abrasive polymers.
AISI M2 Tool Steel is molybdenum based high-speed steel in tungsten–molybdenum series. HSS grade steel M2 is a medium alloyed high speed steel which has good machinability. The H-SS M2 chemical composition gives a good combination of well-balanced toughness, wear resistance and red hardness properties. Widely used for cutting tools such as twist drills, taps, milling cutters, saws, knives etc. Also commonly used in cold work punches and dies and cutting applications involving high speed and light cuts.
Ti 6AI-4V/ Grade 5
Known as the “workhorse” of the titanium alloys, Ti 6Al-4V, or Grade 5 titanium, is the most commonly used of all titanium alloys. It accounts for 50 percent of total titanium usage the world over.
Its usability lies in its many benefits. Ti 6Al-4V may be heat treated to increase its strength. It can be used in welded construction at service temperatures of up to 600° F. This alloy offers its high strength at a light weight, useful formability and high corrosion resistance.
Ti 6AI-4V’s usability makes it the best alloy for use in several industries, like the aerospace, medical, marine and chemical processing industries
GTA also machines grade 1 and grade 2 titanium
Invar is a 36% nickel iron alloy which has the lowest thermal expansion among all metals and alloys in the range from room temperature up to approximately 230°C. The Invar alloy is ductile and easily weldable, and machinability is similar to austenitic stainless steel. It does not suffer from stress corrosion cracking.
