STAINLESS STEEL 304-304H

Dual certified 304/304H is used as a material of construction up to 1500°F. Slight scaling begins at about 1200°F. This is the 0.04% minimum carbon version of type 304 stainless. It has general corrosion resistance similar to the low carbon 304/304L. However, it is subject to carbide precipitation in the heat affected zone (HAZ) of welds. Weldments may be sensitive to HAZ intergranular corrosion in oxidizing acid environments, and to polythionic acid stress corrosion cracking. The carbide precipitation is not harmful to high temperature mechanical properties. 304/304H is welded using the 22Cr 11Ni filler wire (ER308), or covered electrodes (E308). […]

STAINLESS STEEL 410S

410S stainless steel is a low carbon modification of Type 410 stainless steel. Low carbon and optionally a small addition of titanium and/ or columbium minimize austenite formation at high temperatures, thereby restricting the alloy’s ability to harden. The material remains soft and ductile even when the material is rapidly cooled from above the critical temperature. This low hardening characteristic helps to prevent cracking when the steel is welded or exposed to high temperatures. The alloy is completely ferritic in the annealed condition. 410S is ferromagnetic. Chemistry Cr C N Mn Si P S Fe MIN 11.5 – – […]

6Al-2Sn-4Zr-2Mo

6Al-2Sn-4Zr-2Mo A near-alpha alloy, primarily used for high strength and toughness, with good creep resistance up to 1000°F. Forging and machining characteristics similar to those of Ti 6Al-4V. Applications include compressor components, hot airframe skin, and engine afterburner structures. The weldability of Ti 6-2-4-2 is fair, using AMS 4952 weld wire. Several different treatments are available. Sheet & Strip under 0.1875″ thickness: Duplex anneal: 1650 ± 25°F), 30± 3 minutes, air cool, followed by 1450± 25°F 15± 2 minutes, air cool. Triplex anneal: 1650°F ½ hour, air cool, followed by 1450°F ¼ hour, air cool, 1100°F 2 hours air cool. […]

6Al-4V ELI

Low interstitial version of Ti-6Al-4V, for maximum toughness. Preferred for marine and cryogenic applications. This grade is normally used in the annealed condition. Ti-6Al-4V is the preferred choice for the medical implant field. Stress relief 900-1200°F 1 to 4 hours, air cool. Duplex anneal, bar and forgings: Solution anneal 50-100°F below the beta transus, hold 1 hour minimum, air cool. Then reheat within the range 1300-1400°F, hold 1 hour minimum, air cool. Stress – relief annealing is performed after welding. Chemistry Al V Fe O C N H Y Others, Each Others, Total Ti MIN 5.5 3.5 — — […]

6Al-4V STA

Ti 6Al-4V STA (Solution Treated and Aged) is a modified version of Ti 6Al-4V. It is heat treated for high strength in sections under 4″ thick. Ti-6Al-4V has excellent hardenability in sections up to 1″ thick with strengths as high as 165 ksi. For maximum strength: solution-treated and aged (STA) condition is: For sheet, 1675-1725°F 5 to 25 minutes, water quench. Age 975°F 4 to 6 hours, air cool. For bars and forgings, 1675-1725°F 1 hour, water quench. Age 975-1025°F 4 to 8 hours, air cool. Ti 6Al-4V STA is resistant to general corrosion but may be quickly attacked by […]

6Al-4V

Ti 6Al-4V is the most widely used of all the alpha-beta titanium alloys. It is typically used in the annealed condition, at service temperatures through 750°F. However it may be heat treated for high strength in sections under 4″ thick. Hardenability is limited and sections over one inch may not develop full properties. Ti 6Al-4V is welded with matching or with ELI filler wire. Mill anneal: 1300-1450°F 2 hours, air cool. Recrystallization anneal bar for better ductility and fatigue strength, 1750°F 2 hours, furnace cool. For maximum fracture toughness and SCC resistance: Beta anneal 1950°F 1-2 hours, water quench. Then […]

10V-2Fe-3Al

10V-2Fe-3Al Ti-10V-2Fe-3Al is a near beta alloy developed as a high strength forging alloy. This grade provides the best combination of strength and toughness of the commercially available titanium alloys. Its strength permits about a 27% weight savings when compared to Ti-6Al-4V. At the 180 ksi tensile strength level, the K1c value is 40 ksi-in ½ minimum. Solution treated and aged material possesses excellent resistance to stress corrosion cracking, typically K1scc being greater than 0.8 K1c. Solution treated material should not be subject to long term exposure in the 500-800°F range. This could result in high strength but low ductility. […]
