316l Paip Keluli Tahan Karat

316L vs 304L Summary

Ciri	316L	304L
Rintangan Kakisan	unggul, terutamanya dalam persekitaran yang kaya dengan klorida	bagus
Kandungan Molibdenum	2–3%	tiada
Kebolehkimpalan	Cemerlang	Cemerlang
kos	Lebih tinggi	Lebih rendah
Penggunaan Biasa	Marin, kimia, farmaseutikal	General-purpose, low-corrosion environments

Bottom Line: 316L is preferred for more corrosive or chloride-containing environments, while 304L is suitable for general industrial and architectural applications.

Penerangan

316L Stainless Steel Pipe is a rendah karbon, austenitic stainless steel pipe digunakan secara meluas dalam kimia, farmaseutikal, makanan, and marine applications.
Its low carbon content (≤ 0.03%) prevents intergranular corrosion after welding, menjadikannya ideal untuk high-temperature and high-corrosion environments.

316L stainless steel provides superior corrosion resistance compared to 304L, terutamanya dalam chloride-rich or acidic environments.

Komposisi Kimia

unsur	316L (%)	304L (%)
Karbon (C)	≤ 0.03	≤ 0.03
Chromium (Cr)	16–18	17–19
Nikel (Dalam)	10–14	8–12
Molibdenum (Mo)	2–3	–
Mangan (Mn)	≤ 2	≤ 2
silikon (Dan)	≤ 1	≤ 1
Fosforus (P)	≤ 0.045	≤ 0.045
Sulfur (S)	≤ 0.03	≤ 0.03
