Any flower that can emit odor or cause allergies is generally not suitable for indoor maintenance for a long time, otherwise it is harmful to the human body. Such as conifers and flowers, if the number of indoors is too much, it will emit a strong rosin oil flavor, affecting people's appetite, making pregnant women feel sick; geranium, five-color plum, with a special smell, will cause some people to cause allergic reactions; Another example is the smell of jade cloves that has been placed indoors for a long time, which will cause some people to breathe and become bored; the smell of elderberry will make some people feel dizzy and dizzy.

In addition, night cloves stop photosynthesis at night and expel a large amount of exhaust gas, which can make people with high blood pressure and heart disease feel depressed. Therefore, the above-mentioned flowers and trees should not be placed indoors for too long.

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.
