JQ-YJ551K2-1
JQ-YJ551K2-1 is a titanium dioxide CO2 gas shielded flux-cored welding wire, which has excellent welding performance with soft and smooth arc, low spatter level, effortless slag removal ability and optimal bead appearance. It is permitted for all-position welding. The welding efficiency is high. The deposited metal is toughened by trace elements, which has excellent low-temperature toughness at -60℃ and good crack resistance.
The product is applicable for low allow high-tensile welding structural steel with tensile strength of 550MPa, commonly applied in the fields such as ships, bridges, construction machinery, marine engineering, coal mining machinery, construction machinery and so on.

What you cover in your shipping policy and how you communicate it will be highly dependent on your current business operations and supply chain. The goal is to be transparent with customers.
As 2020 brings unforeseen shipping delays and increased carrier costs, it's more important than ever to keep your shipping policy up to date with the following key points in mind:
- Essential shipping details are easy to find. While it is common practice to keep a link to your shipping policy page in the footer of your website, consider how you can also surface important shipping details in the right place at the right time (e.g. on your product page or website banner).
- Clear and concise presentation. Don’t make customers comb through your shipping policy page for the information they need. Whenever possible, make it easy to navigate with clear subheadings, tables, bolded text, and links to learn more.
- Order processing times. After an order is placed, how many days will it take to get it ready to ship? It’s worth communicating if you’re excluding weekends and/or holidays, and if you have certain cutoff times for processing orders (e.g. orders received after 5pm will be processed the next business day). If changes occur within your supply chain, due to peak periods or as a result of COVID-19, you should update your processing times to reflect it.
- Domestic and international shipping options. What are the qualifying regions for your domestic shipping options? International shipping can be broken down in its own section where you list the countries you ship to and estimated delivery timelines. If you offer several shipping options, you can list them in a table so the information is easy to scan. Shipping costs. Break down your shipping costs for the customer. If you have a free shipping threshold, you can communicate in various places as an incentive for customers. Any potential surprise fees should be surfaced too, such as duties and taxes the customer may incur.
