先看应用,再看规格

应用场景会决定标准、证书、表面要求、包装方式和检验时间。

Machine frames and guarding

Square and rectangular tube for load-bearing frames, platforms, conveyors and equipment guards.

Process and transfer piping

Round and sanitary tube for latex transfer, water lines, CIP-ready piping and fluid handling.

Tanks and vessels

Plate and coil for dip tanks, coagulation tanks, drums, vessel skins and fabricated panels.

Hygienic wetted parts

Polished sanitary tube and sheet for latex-contact surfaces where cleaning and corrosion resistance matter.

证书与检验

单证本身就是物流风险的一部分。我们会在出运前区分材料标准、证书类型和检验方式。

MTC EN 10204 3.1

Heat-level test results for procurement and engineering review.

Material standards

ASTM A240 / A554 / A270 and JIS G4304 / G4305 / G3447.

Third-party inspection

SGS, BV or TÜV pre-shipment inspection can be arranged on request.

PMI option

Positive Material Identification before dispatch when grade confirmation is required.

Grade cross-reference

Technical standards are kept readable so procurement, inspection and logistics parties work from the same reference.

EN 10204 3.1 is a certificate standard. Material standards and certificate requirements are kept separate on every quotation.

Grades we can interpret

Dual-labelled ASTM / JIS designations help procurement, engineering and advisory teams read the same specification.

304 / SUS304

奥氏体

304

最通用的奥氏体牌号。耐蚀性与成形性均衡,适用于一般加工设备、机架与槽罐。

ASTM 304 (S30400) / JIS SUS304 / EN 1.4301

316 / SUS316

奥氏体

316

含钼牌号,对氯化物与酸性介质的耐蚀性显著更强。涉及乳胶保存(氨)或腐蚀性介质时的默认选择。

ASTM 316 (S31600) / JIS SUS316 / EN 1.4401

430 / SUS430

铁素体

430

铁素体、带磁、不含镍。适合氯化物暴露较低的装饰件与干燥环境结构件,经济性好。

ASTM 430 (S43000) / JIS SUS430 / EN 1.4016

304L / SUS304L

奥氏体

304L

低碳 304,焊接性更好。焊缝不易敏化,是焊管与焊接结构设备的优选。

ASTM 304L (S30403) / JIS SUS304L / EN 1.4307

316L / SUS316L

奥氏体

316L

低碳 316。卫生级工艺管路及乳胶、食品级设备接液部位的首选。

ASTM 316L (S31603) / JIS SUS316L / EN 1.4404

出运前需要确认的问题

顾问工作会把材料细节和实际物流决策连接起来。

货物能否打包、装箱或缠膜,同时避免表面损伤?
