The reason why the potted rose in summer is dead is mainly because the potting soil is not well-equipped, and the flowers are not turned over in the spring, so the original potting soil nutrients are exhausted, so the rose can not resist the high temperature, which will cause death. There is also a mid-season in the summer high temperature season is almost semi-dormant state, some people see the seasoning does not bloom and then fertilize, so too much fertilization, coupled with high-temperature fertilizer fermentation in summer, will cause the roots burn. Therefore, during planting, the potted rose should be changed in the summer, and then placed in a cool place for cultivation. Potted rose in summer fertilization should pay attention to: control fertilization in 15 days or so to apply a light fertilizer, and then increase the amount of fertilizer in the summer, for the emergence of the already yellow season of the fine-grained soil, cut off some branches placed in the shade. In summer, the potted rose must be sprayed more on the foliage. It is best to carry it in the morning and evening. It can be better absorbed. Try not to trim the potted rose in the summer.

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:
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.
