316L-VV Ultra-Pure Stainless Steel Rods, Tubes, Plates, and Special-shaped Materials for Semiconductor Applications:
After Jiangsu Lianggong¡¯s R&D team absorb the advanced foreign steel smelting technology experience and conduct multiple batches of experimental verification, the smelting process of the ultra-high purity stainless steel 316L material for semiconductor use (UHP) is basically determined.
¡ôChemical composition and processing specifications of SS316L bars, forgings, extrusions, plates and pipes in accordance with SEMI F20-0706E for components of GP systems, HP systems and UHP systems in the semiconductor manufacturing industry.
¡ôMeet the technical conditions of the ultra-pure stainless steel material grade for semiconductor equipment (UHP), and reach the same quality level as foreign steel mills.
¡ôMass production of this ultra-pure material with completely independent intellectual property rights (controllable process stability and good consistency in process quality monitoring).
