Import 4j36-Invar — Buy in Bulk from Supplier in Viet Nam

4J36-Invar is a lean duplex stainless steel with a 21.5% chromium, 5% manganese, 1.5% nickel and 0.45% molybdenum composition, designed as a low-nickel alternative to 304 and 304L. It delivers higher mechanical strength than conventional 300 series grades, enabling thinner cross-sections for cost savings without sacrificing durability. Its corrosion resistance surpasses 304L and matches 316L, making it suitable for chloride-rich environments where stress-corrosion cracking is a concern.

The alloy’s duplex microstructure combines austenitic and ferritic phases, providing a balance of toughness and strength typical for duplex stainless steels. It is commonly supplied in sheet, plate or bar form, with surface finishes ranging from hot-rolled to pickled or polished, depending on application. Industry-standard tolerances for flatness and thickness apply, with typical values conforming to ASTM A240 or equivalent specifications for duplex grades.

This grade is used in chemical processing, marine components and structural applications where weight reduction and long-term performance are critical. Buyers in Southeast Asia and Europe source it for fabrication into tanks, pressure vessels and piping systems. Confirm packaging, MOQ and incoterms directly with Shandong Jintuo Metal Materials Co., Ltd, as these are not specified in the listing but are critical for bulk procurement.

Shandong Jintuo Metal Materials Co., Ltd operates from Liaocheng City, a regional hub for steel tube production in Viet Nam. The company specializes in the distribution of carbon steel, stainless steel, galvanized and color-coated products, as well as copper and aluminum. Its business model emphasizes flexibility in supply chain management, allowing it to adjust production varieties and models based on customer demand and peak construction periods.

The supplier exports to Europe, America, South Asia, Southeast Asia, Africa and Latin America, with a focus on maintaining consistent quality and service standards. While the listing does not specify response rates or verification signals, the company positions itself as a large-scale enterprise capable of handling bulk orders. Buyers should confirm operational details such as lead times and certifications directly, as these are not provided in the available data.
