Canada's PV dual-reaction to China "Timetable December 5, the Canadian Border Services Agency (CBSA) announced the official launch of a "counter-subsidy, anti-dumping" investigation of crystalline silicon photovoltaic modules and laminate products from China. It is understood that The “double-reverse” survey was conducted by Canadian PV producers Eclipsall Energy Corporation, Heliene Inc., Silfab ontario Inc. and Solgate Inc. (hereinafter referred to as “applicants”) who represented Canadian PV modules on October 1 this year. And laminate manufacturers, applied to CBSA for a “double-reverse” investigation of these two types of products from China.

Different from previous PV products surveyed in China, the scope of the survey has been expanded: including PV modules and laminates originating in or exported from China, including other laminates for common transportation or packaging; Thin film crystalline silicon products made of amorphous silicon, cadmium telluride or copper indium gallium selenide. In other words, the thin film photovoltaics that were once thought to be used by some companies to circumvent the “double reverse” will not be spared. The market situation of China's PV industry may be worsened.

In this article, we have prepared a timetable for the Canadian “Double Counter-Research” survey of PV in China, which is for reading.

DUPLEX STAINLESS STEEL

Duplex Stainless Steels Available

Yuhong Group supplies LDX2101, 2205, Ferralium 255, Zeron 100 and LDX2507 in the form of plate, sheet, strip, bar, pipe, tubing, pipe fittings, flanges and weld wire.

Duplex Stainless Steel Overview

Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.

Today, modern duplex stainless steels can be divided into three groups:
Lean Duplex such as LDX2101
Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex usage
Super Duplex such as Ferralium 255 and Zeron 100 and LDX2507

Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
