1 Description TM is one of the next generation of improved high machinability grades from Ugitech. The UGIMA XL TM grades have redefined high machinability stainless steels, showing improvements over the original UGIMA technology. TM is identical in every way to the standard 316/316L, except with respect to machinability. UGIMA XL TM is a proprietary manufacturing process, developed by Ugitech, that has resulted in a product that dramatically increases productivity and tool life, and improves the surface finish on all types of machined parts. TM meets all industry specifications for Type 316/316L. This grade is designed to minimize carbide precipitation during welding to ensure good corrosion resistance properties in many corrosive environments. TM delivers heat to heat consistency that is unsurpassed in the industry and that customers have come to expect. TM can provide a competitive advantage for shops that demand cost competitiveness and reliability. Once an optimum setup has been established, machinists can take advantage of the increased efficiency rates, especially during lights-out production. Classification General purpose corrosion resistant Austenitic stainless steel (300 series). Essentially a modified type 304 with molybdenum addition for added corrosion resistance. Oxidation resistance in continuous service to 1600 F (870 C), and intermittent service to 1450 F (790 C).

2 Corrosion Resistance Environment Nitric Acid Humidity Phosphoric Acid NaCl (Saline Mist) Sulfuric Acid Seawater Acetic Acid Petroleum Sodium Carbonate Behavior It is important to note, maintaining corrosion resistance at weld zones will require cleaning and passivation. TM has excellent corrosion resistance. It is highly corrosion resistant in rural and urban environments that contain moderate amounts of chloride or acids. This grade can be used in the food industry, including direct contact with food, and in the processing industry where ease of cleaning and sterilization are important. TM maintains its corrosion resistance in media such as water, and many types of acidic media such as sulfuric, phosphoric, and organic acids depending on concentration and temperature. TM is also resistant to chlorinated media. This grade effectively resists intergranular corrosion and will pass the following standardized tests: ASTM A262 - Practices A & E DIN AFNOR NFA The corrosion resistance of a stainless steel depends on many factors related to the composition of the corrosive environment, ph, temperature, velocity, agitation, crevices, deposits, dissimilar metal contact, metallurgical condition, as well as the preparation of the surface. The table here is for comparative purposes only and illustrates the performance in different environments. Consult your local Ugitech metallurgist to discuss your application. Optimum corrosion resistance is achieved on smooth, clean surfaces, free from particulate matter such as machining oils, dirt and foreign particles. Under these conditions, parts will become passive in air. Should passivation be required, the following treatment should be followed: Solution: 25% nitric acid at room temperature (68ºF - 20ºC) or at 120ºF (50ºC) for more rapid results. Treatment: Immerse for several hours at room temperature, or minutes at 120ºF (50ºC) followed by a thorough rinsing to remove all residual solution.

3 Heat Treatment The heat treatment (annealing) that gives TM its optimum properties includes heating in the range of F ( C), followed by rapid cooling through water quenching. Hardenability (Cold Working) Not hardenable by heat treatment. Strength and hardness increases upon cold work such as drawing and forming. Forging (Hot Working) Heat evenly in the range of F ( C). Avoid heating core beyond 2235 F (1280 C) during fast forging. Forge in the range of F ( C), minimum forge temperature 1740 F (950 C). After forging, cool small parts rapidly (quench) in water - anneal large parts.

4 Welding TM can be readily welded with or without filler metal using all welding methods except oxyacetylene welding. Oxyacetylene welding can result in carbon pickup in the weld, reducing corrosion resistance. The following are filler metal recommendations: E316L coated electrodes ER316L for TIG wire ER316LSi for MIG wire Weld energies should be limited to the weld areas to avoid hot cracking. No annealing of the weld zone is required as the alloy is designed to avoid intergranular corrosion. Typically the grade can be used in the as-welded condition. However, for severe corrosion environments, the welded structure should be reannealed after welding. Machinability The UGIMA XL TM family of grades is the next generation of Ugitech s high machinability alloys. UGIMA XL TM builds on the Ugima manufacturing process originally developed by Ugitech. This proprietary manufacturing process transforms the hard abrasive oxides normally present in stainless steels into highly specific oxides that are malleable and soft at machine cutting temperatures. At this point, they melt and coat the tool, providing a lubricious layer that reduces cutting temperature and friction. Coupled with precise control of the manufacturing processes, the UGIMA XL TM alloys provide consistency heat to heat, increased productivity, reduced tool wear, improved surface finishes and excellent chip control. Shops quickly recognize that TM does not machine like the standard type 316/316L. TM has provided gains against other high machinability 316/316L alloys, including our own 316/316L Ugima. Compared to 316/316L Ugima, productivity gains of up to 20% and decreases in tool wear up to 50% have been reported. The table on the following page, in conjunction with the recommendations below, provide a useful guide to setup. To realize the optimal capabilities of TM, contact your local Ugitech application engineer. Machinability Table Guidelines 1. The table values are initial suggestions and can vary depending on machine and cutting conditions. 2. The use of coated tools increases the tool life by 20% to 50% using the same cutting parameters, or it increases the cutting conditions (speed) by 10% to 15% using the same tool wear. 3. Tooling grades in parenthesis denote alternate tool material choice. 4. Drill speeds were developed using 118 included angle drills. Increase speeds 10-20% with the use of 130 to 140 angle drills. 5. Drill cutting conditions are valid for hole depths up to 4 times diameter. 6. Machining speeds and feeds apply to highly rigid equipment. Reductions may be necessary on cross slide operations or less rigid equipment. 7. When using C1, C2 or C3 carbides, reduce speeds by 25-40%. 8. Use aggressive tool chip breaking geometries.
