What is stainless steel 316Ti?
316Ti stainless steel is very good stainless steel grade for enviroments which are corrosive. This grade is written as 1.4571 or X6CrNiMoTi17-12-2 according to EN norm and it is written as UNS S31635 according to UNS norm. 1.4571 material has a better corrosion resistance to 316L grade because of its titanium content. Titanium makes 1.4571 stainless steel material more corrosion resistant and also makes the material stronger to friction. 316Ti grade is a really good alternative to 316 grade material and it usually accepted ass a better grade then 321 (1.4541) grade. The Titanium element in this grade is a really hard element to melt it and if titanium does not melted correctly and spread homogeneously, then the machinability will be very low. The titanium element inside 316Ti material also makes this grade better for high degree temperatures. 1.4571 usually used in chemical industries, pump shafts, marine industries.

Applications for 316Ti stainless steel
Construction encasement, doors, windows and armatures, off-shore modules, container and tubes for chemical tankers, warehouse and land transportation of chemicals, food and beverages, pharmacy, synthetic fibre, paper and textile plants and pressure vessels. Due to the Ti-alloy, resistance to intergranular corrosion is guaranteed after welding.

การต้านทานการกัดกร่อน
One of the essential properties of 316TI stainless steel is its corrosion resistance. This alloy contains a high percentage of chromium, which gives it excellent resistance to corrosion in various environments, including marine, chemical, and food processing applications.
การอบชุบด้วยความร้อน
Annealing
To anneal, heat the work piece to 1868-2030°F (1020-1110°C), then cool in water or air.
Hot working
Heat the material to a minimum temperature of 1652°F (900°C) and do not let the temperature drop below this temperature. The ideal temperature range is between 2102-2300°F (1150-1260C), then cool in air after. To ensure the highest possible corrosion resistance afterwards annealing is recommended.
Cold working
Stainless 316Ti has good cold forming properties and are suited for brake and roll forming as well as stamping, heading and drawing. To reduce internal stresses a post work annealing is recommended. Cold working increases strength as well as hardness for this steel grade.
ความสามารถในการกลึง
To avoid excess work hardening keep the cutting edges sharp. Lubricants and coolants should be used liberally to avoid heat concentration at the cutting edges. Chip breakers should be employed to keep the work piece clear.
การเชื่อม
Stainless steel 316Ti can be welded with most common welding methods with or without fillers. Gas welding should be avoided as this will risk carburization. A heat treatment is not necessary after welding and tempering colors should be removed chemically or mechanically to maintain the best possible corrosion resistance.
