Product Description

2205 Duplex Stainless Steel Plate Description

The yield strength of 2205 Duplex stainless steel is more than twice that of ordinary austenitic stainless steel, and it has enough plastic toughness required for molding. The wall thickness of storage tanks or pressure vessels made of duplex stainless steel is 30-50% less than that of commonly used austenite, which is conducive to reducing costs. Moreover, it has good local corrosion resistance, and compared with austenitic stainless steel with similar alloy content, its wear corrosion resistance and fatigue corrosion performance are better than austenitic stainless steel. Whether under dynamic load or static load conditions, 2205 duplex stainless steel has a higher energy absorption capacity than austenitic stainless steel, which has obvious advantages for structural parts to cope with emergencies such as collisions, explosions, etc..

FAQ

Q1: What metal materials do you supply?

Jiangsu Zhongersheng is a professional manufacturer mainly supplying carbon steel, hot-dip galvanized steel, PPGI color coated steel, 201/304/316 stainless steel sheets, coils, tubes and profiles, as well as various steel structural parts. Our products serve infrastructure, photovoltaic, machinery manufacturing, chemical and new energy industries.

Q2: Can you customize material grades, thickness and sizes?

Full customization is available. For carbon steel, galvanized steel and stainless steel, thickness, width and length can be adjusted in accordance with ASTM & EN standards. Profiles can be cut and processed as per drawings, and special steel materials can be customized via production line scheduling.

Q3: What’s the difference between galvanized steel and color coated PPGI?

Hot-dip galvanized steel features pure zinc anti-rust coating with cost-effective and wear-resistant performance, suitable for steel brackets, guardrails and load-bearing structures, and supports secondary painting. PPGI takes galvanized sheet as base material with colorful coating for anti-rust & decorative purposes, widely used for factory roof/wall panels and energy storage housings. Thick galvanized steel is recommended for rainy coastal areas, while PPGI is ideal for decorative outdoor projects.

Q4: Do you have spot inventory? What’s your MOQ?

We built a 10,000-ton standardized warehouse with abundant spot stock of carbon steel, galvanized steel and stainless steel. MOQ is 1 ton for standard sizes; small samples of dozens of kilograms are acceptable. No upper limit for bulk engineering orders, mixed container loading of multiple steel types is supported.

Q5: How long is the delivery time for spot goods & customized goods?

Spot goods can be loaded within 3-7 days; simple cutting & bending processing orders take 7-10 days; mould opening & special steel customization takes 15-30 days, subject to specific specifications confirmation.
