What Responds Best to Deep Cryogenic Treatment?
DCT of carbide and HSS machine shop tooling yields a minimum of 40% increase in wear life. Whether coated or uncoated, solid or indexable inserts, simply treating new or regrind tooling lowers the variable cost of every prototype or production run. End mills, drills, broaches, reamers and all form tools respond extremely well to DCT.
DCT of SAG mill liners, slurry pumps, elevator skips, drills, crusher teeth, paste pump items and other high wear components will reduce maintenance, repair and overhaul by upwards of 30% -while increasing uptime. Whether ductile cast iron, tungsten hardface over alloy steel or moly matrix, DCT increases tensile/yield strength by 5-20%. Use of DCT extends abrasive and gouging wear component life significantly and may reduce comminution cost by up to 20%.
Oil & Gas Items
DCT of blowout preventers (BOPs), risers, couplers, unions and hardware will reduce fatigue cracking, premature corrosion and catastrophic system failure by 30-70% in land-based, sub-sea and deep water applications. This significantly lowers drilling cost, maintenance expense and the risk of environmental calamity.
Additive Manufactured Parts
Additive manufacturing (AM) offers many design, production and manufacturing advantages over "subtractive" manufacturing (milling, lathe turning, forging and casting). However, the AM process often introduces material voids and structural defects during deposition and layering. These contribute to fatigue cracking, fracture and accelerated wear. DCT can improve AM parts by reducing grain structure defects and increasing mechanical properties such as universal tensile strength, yield strength, resistance to high temperature creep, surface finish and wear.
From gas turbines, windmills, nuclear and diesel generators to electric vehicles, industrial compressors and a wide array of power generation equipment, DCT of 8620/52100/9310 and Pyrowear 675 steel gears provides almost a doubling in wear life and a substantial increase in operational uptime. It breaks the ceiling on the 32,000-hour power generation threshold, allows electric vehicles to range further on existing battery life and increases mean time between failure on wind-powered electric systems, nuclear or locomotive turbo-mechanical equipment.
