Vlekvrye staal ASTM A213 TP904L Naatlose buise-handelaar
Graad 304 \/ 304L vlekvrye staal het 'n minimum van 18% chroom en 8% nikkel. Die enigste verskil tussen hulle is die koolstofinhoud. Tipe 304 het 'n maksimum koolstof van 0,07%. Tipe 304L het maksimum koolstof van 0,030%. Hierdie reeks koolstof in die staal beïnvloed die weerstand teen korrosie. 304 \/ 304L is beskikbaar in plaat, plaatrol, plaat, plaatrol, ronde staaf, verwerkte plat staaf en buisvormige produkte vir verdere vervaardiging.<1%) of silicon, phosphorus and sulfur. Localized corrosion attack in chlorides and general corrosion in reducing acids (such as sulfuric acid. It is used in building shells, doors, windows and armatures, offshore modules, reservoirs and pipes of chemical tankers, production of chemicals, warehousing and road transport , food and beverages, pharmaceuticals, synthetic fibers, paper and textile mills, and pressure vessels. Due to the low C content, resistance to intergranular corrosion is also guaranteed under welding conditions.
