Massive Jump in gold prices

In the last 6 Months gold has jumped up in price while other markets have either been stagnant or fallen through the floor who knows how long this bullrun will last and could we see the same happen to other metals this year.

What is the difference between the magnetic properties of 304 and 316 stainless steel?

Magnetic and non-Magnetic Stainless Steel

There are several families of stainless steels with different physical properties. The magnetic properties of stainless steel are very dependent on the elements added into the alloy. A basic stainless steel has a ‘ferritic’ structure and is magnetic, formed from the addition of chromium – it can be hardened through the addition of carbon, making it ‘martensitic’. However, the most common stainless steels are ‘austenitic’ – these have a higher chromium content and nickel is also added. It is the nickel which modifies the physical structure of the steel and makes it theoretically non-magnetic.
304 stainless steel contains chromium (min. 18%), and nickel (min. 8%). It is an austenite steel and is only slightly responsive to magnetic fields. It also contains 18 – 20% chromium and 8-10.50% nickel, and lesser quantities of some other elements.
316 stainless steel is a molybdenum-alloyed steel. The fact that it is also negligibly responsive to magnetic fields means that it can be used in applications where a non-magnetic metal is required. It also contains a number of other elements in varying concentrations.
Type Analysis of Stainless Steel

Steel composition detail
Transformation from non-magnetic to magnetic phases
As both 316 and 304 stainless steels are austenitic, when they cool, the iron remains in the form of austenite (gamma iron), a phase of iron which is nonmagnetic. The different phases of solid iron correspond to different crystal structures. In other alloys of steel, this high-temperature phase of iron transforms to a magnetic phase when the metal cools. The presence of nickel in the stainless steel alloys stabilizes austenite against this phase transition as the alloy cools to room temperature. This corresponds to a somewhat larger magnetic susceptibility than we might expect for other nonmagnetic materials, but is still well below what might be considered magnetic.
However, this does not mean that you should expect to measure such a low susceptibility on any item of 304 or 316 stainless steel that you encounter. Any process which can change the crystal structure of stainless steel can cause austenite to be converted to the ferromagnetic martensite or ferrite forms of iron. These processes include cold working and welding. It is also possible for austenite to spontaneously convert to martensite at low temperatures. To complicate matters further, the magnetic properties of these alloys depend on the alloy composition. Within the allowed ranges of variation of Ni and Cr, significant differences in magnetic properties may be observed for a given alloy.
Practical implications for removal of stainless steel particles
Both 304 and 316 stainless steel possess paramagnetic characteristics.  As a result of these properties small particles (approx 0.1-3mm dia sphere for example) can be attracted to powerful magnetic separators positioned in the product stream. Depending upon their weight and specifically their weight ratio to magnetic attraction, these small particles will be held to the magnets during the production process.
These can then be removed during the magnet cleaning operation. From our experience 304SS small particles are more likely to be held in the flow than 316 SS particles due to its slightly more magnetic nature.

Consumption to bolster aluminium prices after CNY

Consumption to bolster aluminium prices after CNY

SMM Insight 04:33:41PM Jan 23, 2019 Source:SMM

SHANGHAI, Jan 23 (SMM) – Stimulus measures by the Chinese government to boost downstream consumption could buoy prices of primary aluminium after Chinese New Year (CNY).
Even as costs are likely to extend declines, a potential drop in social inventories caused by stronger downstream consumption would rekindle the upward momentum in aluminium prices, SMM expects.
China plans to introduce policies to boost domestic spending on items such as autos and home appliances this year, Ning Jizhe, vice chairman of National Development and Reform Commission (NDRC), said earlier this month.
This is in addition to stimulus measures in the second half of 2018 and upcoming tax cuts.
China’s housing market is likely to see broad-based completion of construction in 2019, which would expand aluminium consumption.
Aluminium consumption declined in January as CNY approached. Operating rates across manufacturers of aluminium sheet/plate, strip, foil and sections are all expected to fall this month.
SMM data for the past decade showed that social inventories of primary aluminium in China staged substantial gains in the two weeks before and after the CNY break.

South Korea, Vietnam and Brazil Witnessed Robust Scrap Import Trade in 2018

The topmost source of import was Japan, whose supplies totaled nearly 3.9 million tons.

South Korea, Vietnam and Brazil Witnessed Robust Scrap Import Trade in 2018
 The import trade data published by government agencies of
 various countries suggests that scrap import trade remained robust during the previous year.
The South Korean customs statistics indicate that the country imported around 6.12 million
 tons of scrap in 2018. This is slightly higher by 3.8% when compared with the previous year. 
The country’s scrap imports had totaled only around 5.8 million tons in 2017.
The topmost source of import was Japan, whose supplies totaled nearly 3.9 million tons,
 accounting for 64% of the total South Korean imports. The imports from Japan
 inched higher marginally by 0.77% over the previous year. In second place was
 Russia with supplies around 920,000 tons. However, the South Korean scrap
 imports from Russia dropped significantly by almost 10% when matched 
with 2017. The U.S. was the third largest supplier. The imports from that country
 witnessed notable increase by 72% year-on-year to total around 860,000 tons in 2018.
Vietnam imported around 540,000 tons of scrap in December last year. 
The imports surged higher by 10.5% from the same month a year before.
 The full-year imports totaled around 5.7 million tons in 2018, significantly
 higher by almost one-fifth. The yearly imports by the country hit 3-year peak
 during the previous year.
The Ministry data indicates that Brazilian scrap imports skyrocketed from 
19,600 tons in 2017 to 267,000 tons in 2018. The primary scrap import
 sources were Canada (99,000 tons) and the U.S. (90,400 tons).

Auto Scrap Metals and Values

If you are an owner of a car repair workshop then Scrap Metal would be something you see quite often, as it builds up so quick you would be more inclined to just give it away to a passing scrap collector.

Our advise would be to hang on to the most valuable items as you would see a steady monthly income flowing back into your motor repair business just by selling these items to a scrap metal merchant.

Car Scrap items worth selling as follows,

Car Batteries
Brake Discs
Gear Boxes
Car Looms
Alloy Wheels
Catalytic converters

Below is a list of items not worth hanging on to if you short of space,

Body panels
Exhaust systems

Reason being they are only light iron which is the least valuable type of metal and you would need 5-10 times more in weight to generate the same amount of money compared to the items on the other list.
