JQ-SJ614




JQ-SJ614 is a fluorine-alkali type sintered flux, which has excellent welding performance with smooth arc, effortless slag removal ability and optimal bead appearance. The content of S and P in welding material is low, and the X coefficient is small, so the temper brittleness of deposited metal is small.



Working with proper welding wire (such as JQ H14Cr1MOR), 14Cr1MOR and ASME SA387 Gr.11Class) for base metal welding, it is commonly used in the fields such as pressure vessels and petrochemical industry.

1. The welding-flux must be baked at 300-350℃ for 2 hours before use.
2. Impurities such as rust, oil stain and moisture must be removed from the work piece before welding.

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.
