从China供应商批量进口304 Stainless Steel Cylinder

The 304 stainless steel cylinder from Fenghua Lingong Pneumatic Componenets Factory is a precision-machined component with surface roughness of 0.4-0.1 micrometres and surface hardness up to HRC60, manufactured from austenitic 304 stainless steel with straightness controlled to 0.15 millimetres per 1000 millimetres and circularity tolerance conforming to GB1184 Chinese national standard.

304 stainless steel contains 18-20% chromium and 8-10.5% nickel by mass, with typical carbon content below 0.08%, giving it excellent resistance to intergranular corrosion and good formability. The 0.4-0.1 micrometre surface finish indicates fine turning or grinding followed by polishing, suitable for pneumatic seal contact surfaces where leakage control matters. HRC60 surface hardness suggests induction hardening or nitriding treatment, as base 304 stainless steel typically measures HB 187-200 (approximately HRC 17-20) in the annealed condition.

This cylinder serves pneumatic actuation systems, hydraulic rams, and precision guide assemblies in packaging machinery, food processing equipment, and pharmaceutical production lines where sanitary surfaces resist bacterial adhesion. Buyers should confirm bore diameter, stroke length, and port thread specification with the supplier, as these determine compatibility with existing cylinder bodies and valve manifolds. The factory operates from Ningbo, Zhejiang Province, a region with established metalworking and pneumatic component manufacturing infrastructure.

Fenghua Lingong Pneumatic Componenets Factory is located at No.2 Chengxin Road, Jishan Industrial Zone, Xikou, Fenghua, Ningbo 317200, Zhejiang Province, China. The supplier is classified as an imported listing on the platform with a harbour trust tier and a response rate of 0.00%, meaning no response data is available to evaluate communication reliability.

The listing provides no information about factory size, year of establishment, number of employees, annual revenue, specific clientele, or ISO certification status. The address places the supplier in the Ningbo-Fenghua industrial corridor, an area known for metal fabrication and pneumatic component manufacturing. Buyers should verify factory registration, quality management system certification, and production capacity directly before committing to orders.
