Rigid CNC Milling<\/strong><\/td>\n304 tends to work-harden if the cutter rubs. We use high-torque spindles and aggressive feed rates to cut efficiently.<\/td>\nOur heavy-duty Mazak machines prevent vibration, ensuring dimensional accuracy even on tough 304 forgings.<\/td>\n<\/tr>\n
Sanitary Finishing<\/strong><\/td>\nMachining parts to Ra 0.8 or better, followed by electropolishing to meet food and medical hygiene standards.<\/td>\nWe understand the “surface trap” requirements for sanitary parts, ensuring no crevices for bacteria growth.<\/td>\n<\/tr>\n
Welding Prep Machining<\/strong><\/td>\nMachining precise bevels and grooves on 304L parts to prepare them for TIG\/MIG welding.<\/td>\nWe provide turnkey manufacturing: CNC machining followed by certified welding services for assemblies.<\/td>\n<\/tr>\n
Large Flange Turning<\/strong><\/td>\nTurning large diameter flanges and rings with tight flatness and seal-groove tolerances.<\/td>\nOur large-swing lathes handle pipe flanges for the oil, gas, and water treatment industries.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Fabrication Guidelines for Stainless 304<\/h3>\n

304 vs. 304L:<\/strong>
\n304L (Low Carbon)<\/strong> is preferred for welded parts to prevent “carbide precipitation” (corrosion at the weld). 304<\/strong> is standard for non-welded parts. Tip:<\/strong> Most modern stock is “Dual Certified” (304\/304L).<\/p>\n

Work Hardening Risk:<\/strong>
\n304 hardens instantly if the tool dwells. Tip:<\/strong> Maintain a constant chip load. Do not let the tool rub. Coolant is mandatory to remove heat.<\/p>\n

Passivation:<\/strong>
\nTo ensure maximum corrosion resistance, machined 304 parts should be Passivated (ASTM A967) to remove free iron from the surface.<\/p>\n<\/div>\n

<\/p>\n

\n

Primary Applications<\/h3>\n

Food & Beverage<\/strong>
\nThe industry standard for mixers, valves, and conveyor parts due to resistance to wash-down chemicals and food acids.<\/p>\n

Medical Equipment<\/strong>
\nHospital carts, surgical trays, and non-implantable devices. Resists sterilization chemicals well.<\/p>\n

Industrial Piping<\/strong>
\nFlanges, fittings, and manifolds for chemical processing and water treatment plants.<\/p>\n

Architecture<\/strong>
\nOutdoor handrails, glass standoffs, and decorative panels that withstand weather without rusting.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
