ASTM A240 316L Annealed stainless steel Plate

ASTM A240 316L hot-rolled steel plates supplied by GNEE meet American standards. Low carbon (<0.03%) improves weldability and reduces the risk of intergranular corrosion after welding. After processing at above 1100°C, they have high toughness, smooth grains and are economical to produce in large sizes. They contain 2-3% molybdenum, and are better than 304 in resistance to chloride pitting/crevice corrosion. No post-weld annealing is required (reducing costs and saving time). They are suitable for ASME medium-high temperature and pressure systems, and have obtained dual certifications of ASTM A240 and ASME SA240, making them the preferred choice for international engineering projects.
