Stainless Steel Bright Annealed Tube
Stainless steel is a corrosion resistant steel alloy with a minimum of 10% chromium. There are different grades and surface finishes of stainless steel produced to accommodate the environment in which the material will be implemented. Unlike carbon steel, stainless steel does not rust when exposed to air and moisture due to the sufficient amount of chromium present. The chromium creates an invisible passive film of chromium oxide that will not let oxygen attack the surface and prevents rusting of the iron base.
Yuhong Group is a stainless steel manufactory of more than 20 grades of Stainless Steel.

·Guangzhou plans to implement national VI emission standards in advance
On the 7th, the official website of the Guangzhou Municipal Environmental Protection Bureau issued the "Notice on the Implementation of the Sixth Stage of National Motor Vehicle Air Pollutant Emission Standards for Light Vehicles (Draft for Comment)", which is scheduled to be implemented on January 1, 2019 for new vehicles and vehicles transferred from other places. National VI standard.
The Exposure Draft proposes that since January 1, 2019, it will be registered in Guangzhou or transferred to Guangzhou's light vehicle implementation country VI emission standards. Vehicles that do not meet the national VI standards will not be able to “sign up†in Guangzhou at that time, and the registered vehicles will not be affected. Light vehicles refer to M1, M2 and N1 vehicles with a maximum design total mass not exceeding 3,500 kg, including petrol and diesel.
According to the plan formulated by the former Ministry of Environmental Protection in 2016, the “National VI Standard†for light vehicles adopts a step-by-step implementation method to set up two emission limit schemes for national VIa and national VIb, which will be implemented in 2020 and 2023 respectively. In the consultation draft issued by Guangzhou, the national VI emission standard refers to the need to meet the national VIb limit requirements, and exceeds the national VIa to directly implement more stringent emission standards.
The national VI emission standard is considered to be one of the most stringent standards for global control of automobile pollutant emissions. Compared with the national V emission standard limit, the national standard VIa emission standard gasoline vehicle carbon monoxide limit is tightened by 30%; national VIb stage emission standard gasoline The carbon monoxide and nitrogen oxides of the car are tightened by 50% and 42%. Not only that, the national VI standard also adopted the fuel neutral restriction for the first time, the requirements for light gasoline vehicles and diesel vehicles are consistent, and also greatly improved the test procedures and limit requirements for evaporative emissions, and increased the recovery of on-board refueling oil and gas. Claim.
Guangzhou plans to implement the National VI four years earlier than the national requirements. In this regard, the draft for comment has set a one-month “buffer periodâ€: the air pollutant emissions of motor vehicles in the fifth phase that have been purchased before December 31 this year. Standard light-duty vehicles can be registered with the official invoice issued by December 31 (inclusive) before January 31 next year. Light-duty vehicles that have been transferred from the field before December 31 this year (including) and meet the national V emission standards may be endorsed by the traffic control department of the public security organ of the transfer office before January 31 next year. Transfer the records and go through the vehicle change registration or transfer registration procedures. Starting from January 1 next year, in addition to the vehicles listed above, if the registration of new vehicles and the change registration and transfer registration of foreign vehicles transferred to Guangzhou City do not meet the relevant requirements, the traffic administrative department of the public security organ shall not go through the registration formalities.
